Crash Report

Thanks! I'll give it a try tonight or tomorrow.

Just tried the new version, but my client crashed while trying to join the server.
Crash Report

The bug has been fixed. On a local server it start without giving any error. The new version(1.2.1) will soon be available on the CurseForge page (https://www.curseforge.com/minecraft/mc-mods/earth2java-mobs).
I'll leave this issue open for a little, in case you still have problems running the mod on a server.

Look like the fluid tag for the mud is still not loaded at the time the game check for it.
Try this, modified 1.2.1 to fix the issue(I hope 🤣 ):

Thank you for the reports, let me know 😃

Get out of the mud!! It's dirty!! 😄
Is a know issue, I'm reworkin th e fluid. In the next update there will be a better behavior for mud.

It works great now. :)
One thing that I've noticed though, when the player is in the mud, I can walk and jump in it as if it weren't really there.

Hi, I think I'm having this same issue on my dedicated server. I'm using forge 31.2.30, and Earth2Java 1.3.2.
