Is this a bug or a new feature?
Today during a Capture & Hold match, while I was waiting for the blue spinning sign to turn red, I suddenly got the message "you will be removed from the map in 10 seconds" ... and it really happened.

It was not a match, that I joined late or after a disconnect. I also was not afk or had connection problems. Very odd.

Arena maps won't end for lack of enemies, but capture and hold will, so you don't get free victories.
In theory anyways, cause the match will go on if it's 10 vs 2 and that's still pretty much a free victory.
