and then there was another one with the magic spiders, I killed one of the spiders inside the cage near the end, it did a slow-mo kill and then I was teleported inside of the cage getting stuck again.
had a problem with my controls too, I got a carriage from the whiterun stables to riften and when I got out none of my controls worked. I was stuck in third person and could only move in one direction with no looking at all. I couldn't save or load my data and eventually ended up falling into the water and drowning. Once it loaded a previous save it was okay again though.
