2 bugs I've discovered:
1. When stopping by Regin's house in the morning, to give him the chest, I didn't see him there. Just Kraka sitting on the floor. So I went into the thieves' guild (no, I'm not reporting Kraka somehow teleporting there, since I know that's been mentioned already) and left. Then, sure enough, Regin's there reading his book. Only... he's not sitting at his desk, he's in the center of his house and- believe it or not- he's sitting on air. (hehe

)
2. I don't know if this has been mentioned, but when standing in front of Eitri's mirror, only the bottom half of the reflection seems to be showing. That's not the whole bug though. I stood there, while listening to his stories and then when he finished and made the door reappear, the top half of my reflection reappeared as well.
Are those reflections supposed to mean anything, by the way? Because every time I play, it's someone different. On one playthrough the mirror shows me as Lithrasir, another I'm Kraka, another I'm... a spectre?
