Random Crash

The steps recreated are unknown. Basically just have it open then use it for a bit. Here are a couple:

I tried and failed reproducing this. The stack trace also doesn't make much sense to me because it indicates the crash happens when adding pseudo attribute constraints and that they are not comparable as required for sorting. The first doesn't fit your description of random crashes and the sorting behavior used should make sure pseudo attributes are always comparable.

Do you recall any details on what kind of actions you did that lead to crashes?
Does it occur rarely enough that I might have simply not played around with the program enough?
Could you provide me with a build file it happens on or is switching builds one of the things you have to do to get it to crash?
If you have customized your pseudo attribute xmls, it would be great if you could add them here so I can try to reproduce it with them.

I did modify my pseudoattributes. Specifically damage.xml https://pastebin.com/q7r6R12M

I use the advanced generator a lot. Been about a month since I've messed around with anything so I don't remember the exact scenarios atm. iirc these would just happen at pretty much any time, but there's a strong chance it's involved with the advanced generator/pseudo attributes I have looking at it.

The crash isn't very consistent though.

Still couldn't reproduce it and have no idea what might cause it. Maybe it'll happen randomly while debugging other stuff at some point.

If it happens again to you, please add the build it happened on. Might be related to that specific build, generator settings and/or pseudo attribute combination.
