Error when trying to run server


So yesterday I created server through hamachi to play with friends, everything worked perfectly fine till today morning when I tried to run the server using start.bat to allocate more RAM I got this error.
When I run the server with the server exe it works fine.
Any solutions? It’s hard to play on mods with default RAM.
Thanks in advance.


Can i see your start.bat file?


@echo off
java -Xmx2048M -jar forge.jar -o true


Try deleting the file level_sponge.dat and restarting the server.


It worked, thank you very much, the only problem is, when I enter the server I get missing registries warning.
Is there anyway to prevent this kind of problems in the future?


What does the warning look like? It should have a few entries of the format modname:itemname.


it says:

Does it matter? Or should I ignore it?


I think it should be OK to continue. Just make a backup of the world in case anything goes wrong.


Okay, thank you very much for your help :slight_smile:
Best regards
