Server crash (Exception in server tick loop)

Hey, my server appeared to be working fine without spongeforge. Upon adding it, I experience a crash. It’s something about an “Exception in server tick loop.”

I’ve tried renaming the jar to include “__aaa” in front to put it on top, yet it didn’t change anything.

Server log:

I think the source might be mystcraft

please help me out here

Mystcraft is unfortunately incompatible with SpongeForge at the present time. The changes it makes to the base game it makes are not something SpongeForge can work around.
