I use the xbox 360 goty edition version of the game and I have Battlehorn, Wizard's Tower, Vile Lair, spell tomes, the razor and dunburrow den all installed onto my xbox. I came back to the game after about half a year or so and suddenly only wizard's tower and dunburrow work. The others don't show up on the map or start the quest for them. Is there any way to fix this or do I have to delete them and redownload them?
