i've not a clue why this is/what caused this to happen.
could be something else of course, i just don't know where to start looking.
i have tried loading a the server without any other mods that require/use trinkets and this behaviour persists
works fine in sp, this appears to be just mp issue
artifacts-4.0.3+fabric
Cardinal-Components-API-2.8.3
cloth-config-4.13.49-fabric
fabric-api-0.42.0+1.16
trinkets-2.6.7

Probably a duplicate of #20

It's a bug likely in Trinkets itself, which never got found/resolved. Neither Artifacts or Trinkets are getting updates for 1.16 anymore.
