[Client] When a team wins a game they lose

So I played a Fley 5v5 game alone, we destroyed the enemy nexus and a text appeard in the chat that we surrendered but there was no vote. And we lost the game. This happened before in an Aram game but they destroyed our nexus.

1. I don't know I guess destroy enemy nexus Not 100% ocuring bug 2 out of 3 games (1 was aram and the other was flex with a flex in between where it doesn't occured)
