Happened to me before. Multiple times. Just happened today except I was on the team that was still alive. We captured all the points and got both Heavy ammo drops and refilled our special ammo. It WAS a close game, about 10,000 for each team at the time. Then we easily pulled away after that. I felt bad for the other team because I've been in their position multiple times before. Not sure why this happenes but it really should get addressed. At least it won't affect Trials of Osiris since it's Elimination.
