Ok, so I cannot get into my house in Whiterun because I get a CTD every single time I click on the door, meaning it is completely uselss to me now. Also got a CTD leaving Mistveil Keep after trying to by a childrens bedroom for my house in Riften (It wouldn't let me, the money was removed but the option to buy remained, I get the same issue trying to swap the alchemy lab for a childrens bedroom in Breezehome).
