Minecraft: 1.19.2
Fabric: 0.15.1
Fabric API: 0.77.0
Queen Cats & Dogs: 1.0.5

Issue: After updating the mod from 1.0.4 to 1.0.5 my instance crashed before even generating a crash-report.

Latest.log: https://pastebin.com/pJCDV9kw

Actions taken: Downgraded back to 1.0.4 and the pack launches again.

Seems like something related to the Queen Cow mixin may not be working properly under your current modpack, probably another mod modifying cows in some way?

It's fixed, the mixin was overriding instead of injecting into the cow.
