Every time I try to play a Spartan Ops chapter that takes place on Quarry or Fortress i can't. I have been able to load and play all other maps/chapters, but Quarry/Land Grab and anything on Fortress it will fail. Quarry will at least send me back to the main menu screen. Fortress never even unlocks the ability to start the mission, telling me:
"Players failed to load Content. A player may be missing downloadable content"
I am not sure what content I am missing as I have installed disc 2 (a few times), and have downloaded and played all of the mission in episodes 1 and 2 save for three of them. I have tried solo and co-op with the same results. Is this happening to anyone else? To 343, what is going on? At least everything else works, but it is frustrating that this issue occurs, as it would seem to be a great mode for co-op and single player. Only getting to play 70% of the chapters just isn't good enough for this mode or this product.
