When loading a recent save game, the camp is covered in darkness. This dark is similar to what ‘undiscovered’ land looks like.
It persists between saves and reloading. It doesn’t seem that I can upload an image yet, so I will link it below.
It just happened on the last load from a save. This town has had significant path finding problems since I started attempting to remove the top of the mountain I am next to, but I am not positive it is related.
