In League of Legends there was a division-by-zero bug with a certain champion and item which caused server to kick all players and then crash. Because the exploiter was being kicked last, their team gets the win while opponents get Loss Prevented because the game doesn't have a normal result.

If the enemy doesnt get loss because game doesnt have normal result, winning team should not get win aswell...

IIRC it was added to the game because of serial leavers (and cheaters, which is funny with this exploit) and then sometime later applied to deal with server instability issues.
