[GAMEPLAY] Game didn't end after a successful surrender

We were playing a game and at 37:52 we got a message saying "Enemy team agreed to a surrender with 3 votes for and 1 against." but the game still kept going until 49:41. Attached is a screenshot for proof. I don't really know what could have caused this but it might affect the game drastically since I, being the typical troll that I am, practically suicided for the laughs.

Looking at the bright side I managed to win a single game twice.
