I am using the USSEP for my Skyrim game for xbox one and its been running great, but i have reached the storyline quest Alduin Wall, and this is when the problem started to arise. A large area of the map has now become inaccessible and crashes within a certain radius of Skyhaven temple. The radius reaches from Soljund's Sinkhole to Skyhaven temple and has prevented me from being able to continue on. Every other area of the game is unaffected and is rather bothersome. I am seeing if anyone knows a resolution without having to restart my entire game or if a patch can be created to prevent the crashing of the game so i can continue enjoying my time with skyrim.
