Something client-side is getting called server side, can't say my mod has that much to do with it, as the Evil Pig never calls anything client-side, which would mean another mod is doing something client-side on the server.

Doesn't appear when Abyssal Craft is Removed.

The crash report doesn't mention a single line of code from my mod, so I can't really see where it triggers from.

haven't used AbysalCraft since the issue, closing report.
