Putting "Trinkets 3.10.0" and "1.20: Cosmetic Armor 1.6.0" on a Fabric 1.21 server. Using "fabric-api-0.100.7+1.21.jar" and fabric loader version 0.15.11.

Sadly, the server crashes when starting it with Cosmetic Armor, but with only trinket it dosn't crash.

Crashes on Client too, with Cosmetic Armour 1.6.0, but Trinket works.

Hmm maybe I should add a github build action to my pr so it's easier to download?
I did contact the owner of this mod on discord like a month ago and they still haven't responded so I'm not sure if this is going to be merged any time soon
