I've been playing Skyrim legenday for about a week and until now have not come across anything that would force me to uninstall or restart my game I just started a quest to find the helm of winterhold after locating the entrance to the cave and entering as normal i see the loading screen then for a split second i see a tunnel then weird red and blue orbs the all i can see is the compass and crosshair when i attempted to pause and reload load was not lit so i quit and loaded 5 earlier saves all have the same error. has anyone else seen this happen?
