initial world state doesn't satisfy preconditions about goap HOT 5 CLOSED

was this a design decision? otherwise, it seems like this ought to be a pretty easy fix, i'll try to put together a patch.

This is an interesting bug, thank you for the easy-reproducer! Thank you for leaving the report open - I saw this when you posted it, but must have let it slip my mind.

This is caused by the backtracking search, in which the preconditions of the action overwrite the goal state such that, for that node in the path, the backtracked goal state and current states do not agree.

This should be solvable, but I need to think about a few other issues whilst I'm addressing this one, namely:

• how to overwrite symbols without breaking the backtracking
• whether to simplify the neighbour finding routine (currently it does a first pass of all actions which can modify a precondition symbol of the action, and in a later called method checks that these "pseudo neighbours" actually satisfy the state).

Any update on this? i believe i have the same issue. What would be a workaround? In the current state it is unusable for me unfortunately.

I've just addressed this and pushed a new version. I've removed the various plan execution modules, because that is highly dependent upon the use case - this package is really only concerned with planning.

I'll update the examples soon. There may be some bugs, but we'll find those down the road!

Thank you for the update, i will try to implement it into my code. The planning is all i need so this seems to be a good fit.
