Logs & scripts
crash log

Version Info (Exact versions only):
LootTweaker: 0.3.2+MC1.12.2
CraftTweaker/Minetweaker: 1.12-4.1.20.698
Forge: 14.23.5.2859 (recommended)
Minecraft: 1.12.2

Additional context
List of mods is included in the log; however, it's worth mentioning there are several mixin and performance mods all stacked together, as expected of a huge mod pack.

It's been a month with no further response. I'll assume this was the same as #92 and close it in 7 days, unless I receive information otherwise.

I think this is the same issue as #92, but I can't tell because the crash report truncates the error right where it starts to get useful

I've found and corrected the bug (4a567e6), then altered the code so it's extremely unlikely that kind of bug can happen again.
0.3.3 is now available on CurseForge with the fix.

I'm leaving this issue open because I'm not totally sure it's the same as #92. Please try 0.3.3 and close this issue if it fixes the crash,
