This bug happens from time to time (it's not rare, nor is it frequent). There are times when being revived I cannot walk away from the spot I was revived from. Sometimes if you are near cover you can stick to cover and break free from the invisible box you are locked into.
Here is a video showing it. The video starts by me spectating a teammate, I get revived then cannot break free from the invisible box.
