For some reason when I upgrade my skills, a few seconds after that they reset back to level 1. I can't figure out as to why is that happening. It didn't happen when I started my world, but later on it started happening. I am using the RLCraft pack if it means anything.

when i download vanilla fix, my game "RLcraft" crashes. there is like a button "Get link" and then it says failed.

Is this the same as #164 ? Was fixed by doing this
I set the "Optimizations and vanilla bug fixes" to false in Mod Options (for VanillaFix) and havent had skills reset since.

Seems that was the issue, thanks!
