SavingFieldCache.getClassFields seems to be throwing a KotlinReflectionInternalError. The issue is discussed more in depth with crash reports here:

ejektaflex/NaturalPledge#4

Did you try the solution i sugguested yesterday on liblib discord?

Yes, the problem still occurs. Interestingly, this only happens in the production jar, and not in the dev workspace.

Oddly enough, my TEs are working even in release, using latest liblib.
I see you're using a fairly old one in dev, and 4.15 in that release test.
Mind to test with 4.16? @ejektaflex

@Bluexin Yeah, I updated mappings to stable_39 and LibLib to 4.16 here. Still no luck in release.
