Great game, really enjoying it. I just wanted to point out a couple of bugs I've found. Apologies if these have already been discussed, couldn't find them by searching.
1. One of my characters has one apparently empty inventory slot but the game still says it is full when I try to pick up an item. It is always the same slot. I can fill up all of the other slots except for that one.
2. It is possible to get inside the Hill Giant fort when the barrier is up (i.e. haven't completed the prerequisite quests). Just initiate combat with one of the Hill Giants near the entrance and move into the fort during combat. After doing this, the barrier remains and prevents you from leaving once inside.
