Currently playing on Medieval Minecraft v19.5 and I added the cosmetic armor mod myself because I like to look good, but I had a crash after equipping armor from the Bumblezone mod mid-flight with an elytra (from icarus) and would continue to crash upon opening my inventory until I removed this mod

I posted this in spite of similar issues existing since most of them lacked logs

Mentioning #17 because this crashlog is similar, and I only crashed after I had equipped the bee chestplate too

upon further research I found that telepathic grunt opened an issue in better end since this is apparently their problem so uh closed ig :)
