Eh, I'm terrible at explaining things. But it seems that a bug occurred at the end of the map Base Race, and the timer stopped. One of the two teams need to score 1 so the game can continue.
Then there was an argument , some ppl stopped resisting, some ppl continued shooting. Well, in the end, Rabit(I didn't catch his name) came back with an objective and for some reason he refused to "BRING IT BACK". So there were like 7 - 10 people surrounding him and pushing him. There was an awful amount of yelling and cursing at that time.
Lol, it's like watching ice hockey.
