Self-destruct Bug

Just imagine this:

Your going at it with your team. Half way through it, you get attacked by predator and you manage to get him into second wind. You track him down and finish him off. You then knock off his mask and get him to the floor, but as soon as you try to deactivate it’s self-destruction, it renders you unable to move and your unable to disarm it. This has happened every time I’ve been in the situation with the predator since the 1.06 update. I love the game and would love for this bug to be fixed.
