Started a new game, female Nord. Been having a buggy time. Notable events:

1. Partners disappearing. Have lost two so far. Did the "go to prison" trick to solve this, but still don't want this to continue.

2. Deflecting arrows. I fired an arrow at a bandit, the arrow hit what seemed like an invisible force field about twenty feet in front of me. Dropping the bow and equipping a new one solved this.

3. Attacked by the infamous invisible Kajeet. A common occurrence but in this case I lost my second partner.

4. When I equipped the Familar Staff in my left hand and used it, the familiar didn't appear although the lights and sounds happened. If I equipped it in my right it worked.

5. Had the issue where I couldn't draw my bow or use my spells. Fast traveling solved this.

My first time through Skyrim had none of these probs. I did lose a partner once but she returned. I don't get what has changed since then.
