[1.12.2] Crash when Start server

[Ibirtem]

After loading the main world, a little time passes and the server crashes. I try mystcraft 7.03 and 7.04 Crash anyway. https://gist.github.com/Ibirtem/e2091cb722e03c6825db3147f6f1192c

Idk why but in single player everything is all right.

I wrote up a wiki page that may help with getting info on this : Bug Reporting Best Practices

Looks like it might be a mod conflict with the baseline dimension profiler. One possible workaround is to disable that in the configs.
