When i try to install any version of this mod in the 1.3.0 version or above, I play in the 1.16.4 version of the fabric API, the game crashes and sends me this message:
---- Minecraft Crash Report ----
// I bet Cylons wouldn't have this problem.

Thanks!

I think it is a silly mistake of mine, I'm new programming so if anyone can help me i'd be very thankful.

Make sure you're using the latest version of Fabric API.

Any particular reason you're on 1.16.4? Most if not all 1.16.4 mods should work on 1.16.5.

Ok, thanks!
