I had a challenge to get 10 kills with the pulse carbine. I noticed it was never updating from 0/10 so i figured it was just a visual bug and still keeping track behind the scenes. Well after keeping track manually of my kills I ended up with at LEAST 15 and it still did not complete so I had to use a challenge skip on it.
Speaking of broken challenges, how are you supposed to “Kill an enemy vehicle by grinding the choppers wheels” because it certainly does not work the same way as halo 3. I have rammed 4 vehicles in pvp with the chopper and not a single one has been destroyed. My chopper always just flips over and I fall out and die. Considering the only way to level the battle pass it to complete challenges maybe make it so they are actually possible. Thanks,.
