I've ran into a few annoying things in Skyrim so far.

I married Derkeethus the Argonian but there's a problem, I told him I wanted to move to Breezehome in Whiterun but he just goes to Darkwater Crossing, then when he gets there he walks so far out of the village then turns and goes back, and so on, I even tried telling him the same thing while he was following me and we were standing inside Breezehome, but he leaves the house and goes back to Darkwater Crossing and does the same thing, I've tried this in all the houses I own so far and it's always the same. And today something popped up that could be serious if it carries on, I was doing the quest called The Book Of Love and was at the point where I had to bring Faleen's letter to Calcelmo, I spoke to him about it but something went wrong, after he said "I have to see her, please excuse me." the character interaction menu didn't close, I tried pressing X because that normally works, but I had to press O which meant that the conversation didn't count so I had to tell him about the letter again, and again it happened, so now I'm stuck unable to carry on the quest, and the same thing seems to have happened to Derkeethus, I asked if the store had made any money and everything but the same thing happened as with Calcelmo, if this problem gets any worse it'll break the game I'm fairly sure, please Bethesda, fix these issues.
