Server Crashes when Adding Sponge

Sponge Sponge Support
1

I spent 3-4 hours tinkering around and I can’t figure out why the server crashes when I add sponge!
I checked similar cases but none of them had a fix that worked for me. I also don’t have AE which seemed to cause a lot of the crashes. I even tried removing some of the other coremods, but no luck there either.

Note: The original works mudpack works, but crashes when I added SpongeForge

This is a known issue with yunomakegoodmap. For now, you’ll need to remove that mod and anything that depends on it.

Sadly, I uninstalled that mod and ItsBecauseUHasNoGoodSpawn mod. This did launch the server, however, it makes it so playing the Skyblock is not possible. Any other fixes??

Edit: FTB Launcher (Sky Factory 3 Modpack)
