Re: M-COM not exploding in flashpoint rush match.
Update, this is not flashpoint specific. this can happen on all maps.
Here's a screenshot of el alamein rush match where m-com got stuck in detonation loop and where it didn't explode not matter how many times you defused and planted it again.
So far I've experienced this game breaking bug 7 times in these recent few days.
This was the worst one where the game lasted 3 hours due to game not ending when tickets went to 0.
In my experience every third or fourth rush match gets stuck due to this bug.
