I'm curious if this helped because I did exactly this and I'm still getting black textures and crashing while trying to load my Hundings. I've took down at least 100 of my decorations as well, especially animated ones and it doesn't help still. If I happen to log off with my character in Hunding's then I can't load them. I have to log in with another, travel there, make sure I exit the house then log off. Then I have a chance of logging in with the character stuck in my house.
