Hello,

As i've see, you're adding a lot of special features who are not an exploit to your plugin.

I'm requesting something to block the ability to someone to repair an amor or a sword if this one have a special name or a special lore.

Best regards,

Hello,

The BlockRepairsInstead is removing the item when you put it in the anvil with a Shift click (Tested with item lores check in 1.14.4). It's removing the item only if the lore match.

Config:

ItemRemoval:
ItemNamesToRemove: []
ItemLoresToRemove:
- 'Durabilité'
RemoveItemsMatchingName: false
NameLoreStrictMatchMode: false
BlockEnchantingInstead: false
BlockRepairsInstead: true

Best regards,

Hello,

It seems there's a new way to crash servers with armor stands, here is a video: https://www.youtube.com/watch?v=j41QWhuBp8M

I found a plugin who is fixing that: https://www.spigotmc.org/resources/%E2%AD%90-armorstandcrashfix-ascf-say-no-to-armorstand-crashers-%E2%AD%90-1-8-1-15.72634/

But if you could implant a fix in IllegalStack, would be a good thing :D

When enchanting books using enchanting table, what enchant you choose in the GUI does not always match what enchant the book is given. Example: Choose 'sharpness I' and you get 'knockback I'. This is not happening when 'illegal stack' plugin is disabled or removed from server. Besides 'illegalstack' server runs the plugins Clearlag, Matrix Anti-Cheat, ProtocolLib, and SaveDeathDrops

Snippet of illegalstack's config.yml:
Enchants:
FixIllegalEnchants: false
EnchantedItemWhitelist: []
OnlyFunctionInWorlds: []
AllowBypass: false
RemoveUnbreakableFlag: false
RemoveCustomAttributes: false
CustomEnchantOverride: []

This issue aside, my hats off to the makers of this fine plugin. My semi-anarchy server could not function with out it.

Players cant have more than 1 water bucket in inv or it takes ti away! How do i fix this?

When you set an item in the enchantment table ( http://prntscr.com/r9ingh ) , if you click on the lapis slot (but without setting anything) the levels of the enchantments are going to change ( http://prntscr.com/r9inse ).

It works also if you set and unset the item or lapis several times.

When I trigger the StoppedPushableEntity event, it will cause the entity to disappear. This may cause losses to some players. Should the movement of the piston be prohibited? Instead of deleting the entity?

Hi, I couldn't find anywhere on spigot if it's open source or not, and the repo has a GPL license leading me to assume that it is?

As noted in the wiki, the option to notify instead of blocking is very spammy. My use case is that I would like to allow TNT duping on a small scale. I want to be notified if a TNT duper exists, but not every time that it runs. A possible solution could be to notify the first time the duper goes off, and then mute any duper at the same location for a configurable amount of time? ie 5 mins. This way it would notify again if it is still running after five minutes, and multiple dupers or a flying moving duper would still spam the admin.

This part is a separate issue: I have noticed that TNT dupers are blocked/notified when PreventRailDupe is ON but PreventIndirectTNTPowerDupe is OFF. This means to allow TNT duping both have to be OFF, meaning you cannot independently allow them, they are linked. Edit: It also seems PreventIndirectTNTPowerDupe is unable to be set to notify only, even when on the notify only list it blocks duping.

Hello, your plugin is awsome but it does not work with Customizable Armor Stands datapack by Xisumavoid. When i spawn an armor stands book it works as intended. But when i try to work with it for a while, i get chat error: [Illegal STack] - Unknown and my books content changes to: Illegal book tag. Please help :(

Every time I insert an item into the Enchanting Table and take it out, the level for enchanting this item changes (between 21-24), I don't really know why. I generally noticed that if I disable the "Illegal Stack" plugin, this problem does not occur, I tried to change options with "enchant" in config but I don't really want to work. I am asking for help and thank you

When a mod clicks the teleport on IllegalStack alerts they're told they have insufficient permissions. I found that command as shown below, but there doesn't appear to be a permission node for this?

Hi,

Can you add something in item removal to block a specific item ID ?
I want to disable shulker boxes :/

Best regards,

When I restart my server after changing IllegalStack's config.yml, it changes back to what I believe is the default file. Am I editing the config the plugin the correct way, or is this unexpected behaviour? I'm on v2.0.7, and I can't find anything in the console saying it will be reset.

When disguised with LibsDisguises, you can see yourself as a mob (selfview)
It's technically like a mob is following you while you are vanished. Or something like that.

When you try to pass through a nether portal, you get stuck on the destination side of the portal. The mob is not allowed to pass due to illegalstack preventing all mobs from going through portals.

It would be nice if illegalstack can see the difference between normal mobs and mobs created by LibsDisguises so a disguised player can still pass.

books are stackable up to 64 but the plugin detects it as an 'ilegalstack' and removes it. Please can you fix this?

Hello. Basically I use unsafe enchantments with tim the enchater and such, and I wasn't sure exactly if this plugin removes enchants like prot 8 etc.

I'm on 1.12.2 Paper and the toggle command seems to do nothing.

I manually edited the config file, did istack reload and it still kicks. I even shut down the server, edited the config file, started the server, and it still kicks.

(The plugin counts this as a dupe when the piston retracts)

Here are three examples that won't cause the rail/carpet to dupe in vanilla when the piston is activated, while the plugin still counts it as a dupe. I'm on an 1.12.2 server and this makes it troublesome and somewhat annoying to build certain redstone contraptions that requre moving carpets/rails (obviously without duping them).

When portal dupes is blocked, and BlockNonPlayersInEndPortal: true all dropped items are rejected. Which works awesome.

When the dragon exists, the portal is gone and the fountain is empty.
When the dragon is killed right above the fountain, and it drops (custom) loot. The loot falls into the empty fountain. After the ender dragon explodes, the fountain is recreated.
All dropped items that was in the empty fountain, disappears.

Is there a possibility to reject items laying on the bottom of the fountain when the portal is recreated?

When I try to harvest crops by water, the plug-in will make the crops disappear. How should I turn this option off? Or is it a plugin vulnerability?

Sometimes the notifications can get a bit spammy, and would be nice for admins to be able to toggle it on/off.

Command idea: /istack notify toggle

removing and replacing or changing the size of the lapis stack changes the levels randomly, sometimes as high as 33

Add a config option to run a command as player when they get stuck in a portal, opposed to breaking it, i.e. /spawn.

Server: Spigot 1.8.1

Is there a way to turn off the debugging?

Hi,

On my server, players are affected by BlockPlayersAboveNether option but it's disabled.
I've tried many thing like add nether world in ExcludeNetherWorldFromHeightCheck, with command, same issue after a server restart.

We using Paper 1.15.2 and IllegalStack 2.1.2a

Could you fix this please ?

Sincerely,
Fabien

Hello, PearlPhasing doesnt work when i try to bypass glass (not glass pane).
1.15 paper 260

Regards.

One of my players discovered a bypass for nested shulkers.
He can place a shulker in a shulker by a trick.
I'll send the details via discord.
Using version 2.0.10c

Just like in the video, as long as you get 3 shulkerbox books filled with Chinese characters, you may disconnect the player, because many people on my server banned others like this, thank you

It appears there is no string to in messages.yml to change this autofishing message: https://i.imgur.com/5a0T4D2.png

Hello,

There's an exploit with heads, dropped from a player. (I just have a way to get the head of a player).
Here is a video: https://youtu.be/wYfTewrRihM

I don't rly know what is this exploit, but this is crashing most of players in the range of the guy who have the head in his hand.

I would like to request an option to block the use of pistons in slime and honey blocks.

This would avoid flying machines (machines that move in one direction indefinitely with a redstone clock).

It would also avoid farms with this type of objects that move a lot of blocks with a piston. For example I have a piston limit per chunk and my users use these blocks to bypass the limitations.

This should also lock the lock of a block that is attached to one of these blocks (slime or honey) to move them indirectly.

Hey, I enabled the setting to true in disabling zombies from picking up items, however, they're still picking up items, which causes them to dupe the item on death. Is there some other setting I had to enable first?

Server Version: 1.14.4

I turn "KickForAutoClickerFishing" to "false" in config or use command "/istack toggle KickForAutoClickerFishing" to disable it, but it still kick the player who use AutoClicker to fishing.

When 0-tick farm detection is on, it detects this lossless (not 0-tick!) sugarcane farm by TangoTek as 0-tick and removes all of the pistons and dirt. This bug is 100% reproducible by building more than one layer of the linked farm and letting it run for around 2-5 minutes.

On a skyblock server a portal was shut off because blocks are to close to the portal

  NetherPortal:
    PreventPortalTrap: true

In this case I think istack could have overreacted a bit. On my server, blocked portals are not really an issue, so I'll turn it off.

But for the sake of improving this protection, I'll give details.

On one side: you see fence gates. The full block beneath it are on the same level as the obsidian.

The other side is probably the issue. There are normal fences on slabs. The slabs are half a block above the obsidian.
So the player can leave on one side.
I reproduced it by making this:

And it broke after several times teleporting through it.

I'll disable this protection on the skyblock game. It's not really necessary anyway since players can easily teleport to their island by commands.

My users cannot use the boats in places where they do not have water. Is there a way to disable this?
