Whenever I try and run it (with just this mod in there) it crashes.
Crash log:

Steps to reproduce the behavior:

1. Start game (with Adorn, Kotlin, and the API)
2. Wait a few seconds
3. See Error

Expected behavior

The game should start normally (I played on 1.16.5 prior to this)

Additional context (Optional)

This is probably really easy to solve, however I've tried to fix it on my own, so ignore my ignorance if this is easy!

It looks like

1. You don't have Fabric API in your mods folder at all (Fabric Loader can't find it)
2. Your Adorn is outdated as well, try updating to 2.3.1 (if you happen to have multiple adorn jars, remove the other versions)

Ah, thank you! I could have sworn I had it in there!
