I'm playing on XB1. I use mods. So far its been great. But today I installed the polymorphing mod. And when I use it is shoots me up into the sky and I can't move up there. Well I tried it in a ruin, and it turned me into a bear, and I died. I deleted the mod and reloaded. But now collision detection seems to be completely broken. I can't walk on the ground and I can't jump. I can walk through the floor, I can walk into the sky, I can walk trough anything. This has affected every one of my saves on every character and starting a new game does not help.

Please help me! This is for Xbox 1 so I do not have access to the normal PC fixes.

Did you save while the mod was activated and reloaded that same save after removing it?
