I can't really tell you why this has been happening. But I can tell you that this problem is not unique to you. I've been having this same glitch and it also affects my powers. I run behind cover whenever this happens and come back out. It seems to solve the problem most times. If not, then the issue may be extreme lag and it goes away by the time I get out of cover. I know it's not much of an answer, but I hope this helps.
