I'm not sure how it happens but sometimes you get caught in a TRAP and it disappears and you cant get out
The only way to get out from my experience is getting into another trap with someone near you and they get you out asap
more detail
Your camera is locked in the same position if you we're still trapped and your ASWD movement keys dont update as in if you look left and move you'll still go straight
