Hey for some odd reason every time I place a rolling Mill down, My game just completely crashes. I've run into the past when I placed a shaft that connected to another shaft that had a cogwheel on. It hasn't happened in a while though. Now it's just crashes me, but my friend doesn't crash.

May you send the crash log?

I'm unsure but this may be it. He has the rolling mill so maybe?

Also this Create mod is part of a modpack called Craft to Exile.

The Rolling Mill is part of the Create Crafts & Additions mod, not the base Create mod, so you should probably open an issue with them.
