Issue
When I add this mod to my fabric server I cannot launch it. So I stripped it down to only Fabric API and More Axolotls but it still persists.

Mods
fabric-api-0.43.1+1.18.jar
more-axolotls-1.0.0-1.18.jar

Server Log

Its weird because it seems like it cannot find the screen class but I guess if thats what it fails with it won't be the only thing being wrong.
I suppose that's a problem caused by something from you, that doesn't occure with any other mods?
Have you tried to reinstalling the server?

Okay nvm I found the problem and its really really stupid, thanks for reporting this

Np ;)

Gonna upload a fixed version soon

Fixed versions released now :)
