I've heard of this happening with Acceleration Wand from "Not Enough Wands" so I removed that mod, but it's still happening, even on a new world. What mod is causing this? Here's my mod list: https://pastebin.com/jbqDwuMy
EDIT: I figured it out with process of elimination. The Oops mod doesn't play well with Pam's Harvestcraft. I also tested acceleration wand and it wasn't causing any problems.
