Immersive Railroading is causing our server to crash if client's get near a certain chunk. As nobody from us can actually get near it, this is the only description I have of the setup:

"That large square of cobblestone is where I have been testing the immersive raliroading mod. I had an idea of using a mechanical user to place track so I could use a model hand car, but instead of finding the right settings to lay track, I found the settings that WILL crash the server. Right now I think if I log in the server Will Crash again. Sorry for the migraines this will cause."

Closing due to A) changes in modcore B) I don't want to support this
