"Preparing spawn area:" changes to "menu.preparingSpawn" and does not give a percentage anymore, something to do with changing language?
This is the only thing I noticed changed in the server text output.

Minecraft 1.18.2
Fabric loader 0.14.4
Fabric api 0.51.1
Mod ver 2.5.1

Oops! I'll try to get a fix out tonight.

I just uploaded version 2.6.1 which should fix this. Thanks for pointing it out!
