Hey im a part of a minecraft servers development and owner team that just recently is swithing from spigot plugins to forge.
we currently are trying just one mod (ImmersiveEngine) and it worked just fine for a while, but now everyones client crashes with an exit code -1 at the same time.
¨¨
The game crashed whilst unexpected error
Error: java.lang.IllegalArgumentException: null
Exit Code: -1

I can provide crash reports if necessary.
Any help would be appreciated.
Thank you.
