I can never seem to jump out of it. Jump is either disabled or clicking on it won't do anything at all. All I can do try switching character and if that doesn't work I have to teleport back to camp.
Yep, same for me. I've not had the endless run happen in combat yet, but when they did get stuck the only thing that seemed to help is teleport. Clicking to another character doesn't seem to help. I tested it a bit more, and another issue with this glitch is that the characters no longer seem aware of each other, so I end up with 3 characters overlapping, all running in place.
