Strange and physics defying bug

So was playing me some MNC yesterday when a strange bug occurred. We had just dropped the enemy teams moneyball and we were about to win the game when a sniper killed me, sending me to the overhead map. The map showed a group of gremlins spawn, which made sense as they had an assassin, but then the gremlins flew across the map and downed our moneyball instantly. This was on grenade III. They took about 1 second to travel the length of the map directly over the middle.
