  I change file "AppliedEnergistics2.cfg" in line 226: AppliedEnergistics2.zip - I have crash
  B:DecorativeBlocks=true - no crash
  crash-2023-10-02_20.28.13-client.txt

it seems that this bug also appears on the original AE2 Unofficial Extended life.

Maybe you're right. In that case, we need to do something about it:

1. Fix the bug.
2. Remove the defective parameters from the configuration file.
3. Write a warning about defective parameters on the title page of your mod.

I will try to test other things in the config on "pure" minecraft (without other mods). I would like to disable the extra items in the mod, but the bug does not allow this to be done.

should be fixed in v0.3.1.4 (https://github.com/beecupbe/ae2uel_extended/releases/tag/0.3.1.4)

Thank you very much! The bug is fixed, I checked.
