Invisible walls and an unconscious notification
When beating goblins to a bloody pulp I kept coming across the same issue wherein after combat as I was running off giggling I would suddenly hit an invisible wall almost like a lag spike. I would be unable to go in any direction for more than a couple of steps. About three seconds after, I’d have a false notification as if unconscious and on a timer to regain control. This would persist until the phantom timer ran out and I was able to be on my merry way.
