Change surrender system from [Yes Votes/number of online teammates] to [Yes votes/total votes]
for example: 3 people say Yes to surrender and the other 2 dont vote = [Your team agreed to surrender with 3 votes for and 0 against]
2 people say Yes to surrender, 1 say No, 1 doesnt vote, and 1 ragequit = [Surrender vote failed 2/1]
