On harvester big demo the other night i was in a room, we planted the bomb,then killed the other team and the thirty seconds went by and the bomb didn't blowup .It just went back to the windmill and one of there guys came back alive we killed him and planted again. It still didn't blowup so we threw nades on it and they both blew up but time ran out and no one got a win. That was the first time I've seen that .
