Issue description

I guess it's not working on 1.18.1, but you mentioned:
Revert "Allow 1.18.2 version on 1.18.1" - MelanX

Steps to reproduce

Start server

Other information

No response

Yes, I reverted the previous change called "Allow 1.18.2 version on 1.18.1". This reverts the ability to use it on 1.18.1.
Mojang did a few changes which makes the 1.18.2 versions of the mod incompatible with 1.18.1. To be clear, it's basically one single change which affects this mod.
Since mods are updating to 1.18.2, you could use the 1.18.1 versions for now and update in the near future to have all the new features and fixed things.
