I take it this is one of the old bugged Voidstars where the attacking team was spawned to the next spawn point (bridge) before actually clearing the door. Then spent the rest of the time planting bombs on the backside of the door while the defending team defused without opposition. Am I right? Happened to me twice when I was Imperial, and never in my favor. Judging by the high distribution of objective points and the low damage and healing, this was either a joke match where everyone planted and defused and sung songs, or the bug I described. Regardless, calling BS.
I was thinking the same exact thing Flak, or its a setup game, but the bug seems like a more viable answer.
