I have a hunch on this. Right now teleport orbs aren't being cleared properly when you restart the game, so it looks like it's looking for some object in the world that belonged to the *previous* world in which the orphaned teleport orb belonged. Will dig into the log in the e-mail. Any bugs that cause crashes are super high priority so thank you!!
Not sure if it helps, but I had an orange teleport bubble with me and had just started a run having just teleported up to that camp. There were certainly other orphaned orange bubbles strewn about though. Not sure how I got hurt there, I guess if it had to do with dangling references or something all bets are off.
