(I do have a large number of mods running on my client but this has never been and issue before so I don't think it has anything to do with that.)

Recently in my game, whenever I save, quick-save, or auto-save in riften, and only in riften, my game crashes. I don't know what the cause of this can be and its only inside the city of riften the buildings within it, I can save just fine from the stables or dock.
