1. You are correct and I don't know how I missed that! Thank you! I'll see about correcting that.
2. Yes, the starting location should be determined with a d4. Somehow the (d4) got eaten by the layout
3. You can't scavenge an occupied room; you get rewards by interacting with the occupants. In retrospect I can see how that might be confusing.
Thank you very much for taking a crack at the armory!
