Some unreachable containers:
Camp Hathor: Can't access the footlocker inside the backroom of the leader's house, since it's apparently facing the wall.
Foundry: In the area west of the main area (main area being where the shops and the bar are), inside the middle house at the southern edge of the screen. In the room with the a shelf and two lockers, the locker closest to the shelf can't be accessed.
Atop the tower in that western area, walking from one ladder to the other, I am suddenly walking on air instead of where I should walk. The walkmap seems to be incomplete or non-existant here.
General errors:
The item "Pig Leather" has the description for Rathound Leather.
When talking to Silas about the start of the final attack on the Scrappers, he says "Your SGS buddies will be attacking from the north[...]". However, I didn't manage to convince the SGS, so it should be the Protectorate instead.
