When I go inside the tower all is black only slight color where the spells on my hands should be. If I cast magelight it is still dark only some shadowy outlines in blue like a poorly developed photo. If i turn around I see, instead of the door, an open way to the outside that when I try to walk through teleports me to the second floor of the tower. If I try to walk around the secnd floor of the tower it teleports me back to skyrim right outside the tower door. Is this a known bug or just me? If you didn'tread the description this is the Blue Stripes Monsterwars tower in Winterhold.
