I'm calling this the 'Zap Bug' for lack of a better name. I think -- or hope-- everyone has seen this a few times. It seems to be server side, though sometimes it can only be on the client too. I'm not even entirely sure how this happens.
So, I'll explain what I know, assuming someone hasn't seen it. If you go and touch the RC (I've seen it happen through walls and floors), and walk away, you look like you're still getting zapped. The shock doesn't go to anyone in particular, just to other random team members (I've yet to see it go to a building or an enemy).
If there's a topic on this, please point me to it, as I would kill to help with what I can. I'm going to try to record demos or screenshots of this bug.
