There are some buildings in the game that seem to not spawn loot at all.
There are two which stood out to me:
- The wooden blockhouse that was already enterable in the mod. Never found a single peace of loot in one of them, although the surrounding buildings did not seem to be emptied out already.
- The "big" barn with multiple stairs. Never found anything in one of theese.
I am pretty sure there are more buildings. Maybe someone wants to add or specify something.
