Halo 4 bug, Game breaking bug!

So, I have encountered a game br****eaking bug for halo 4! I had an issue with playing halo 4, on the mission 6 Reclamier. Now, I can play it fine. However when I want to save and quit it. I come back to it loading up error with red text in the top left hand corner saying "__Untracked build, won’t upload." Now, I can play every other halo game fine. In fact I beat all of them on heroic alone. But when I got to this specific level, this happened. Now I know the obvious thing to do is beat it in one go. But that still shouldn’t be the resolve of this issue.

Also, as anyone had the issue with not getting there 10$ back as promised for preordering this game? It’s been over 2 weeks, and haven’t gotten anything.

Also, this is NOT undeserved hate towards 343. While I was a bit disappointed with the lack of game types in the multiplayer. I still found this worth my money. I know it’s not their fault as for any intelligent individual to put together the pieces it wasn’t their fault. As stated in their video of making halo 2. They needed more time. They don’t make the deadline, Microsoft does. I just want to make that clear.
