Oaken Waters opens at 14:00 I went at 13:50 and waited for the opening, I suppose the NPCs spawn at the moment its open, well... the faceless NPCs in Oaken Waters were stuck on one of the left doors of the main building.

Another time, I when at 19:00 and 4 faceless NPCs were there wearing towels on the change room but no moving, just one in front of another.
