Just after the first Heavy ammo drop, my opponents' team stopped losing flags when we captured them, and my team stopped gaining flags when we captured them. In the game world, they were functioning normally, but in the scorekeeping, they weren't. Also, the heavy ammo spawned twice. At one point, the scorekeeping showed my team with 1 flag and the opponents with 3 flags, for a total of 4. After losing point A, we never got another flag again as far as the scorekeeping was concerned. We finished the game holding both points A and B, but with zero points captured on the scoreboard, and our enemy with 3 points captured. Despite literally everyone on our team having about a 1.0 k/d, this bug was insurmountable as the enemy was getting 300 points per kill to our measly 100.
