Sorry for the delay.
My issue may be related to those issues, but doesn't appear to be exactly the same. My issue seems to be on a wall surface, but if I get close enough it will refresh the lighting, but when you log off and log back in the "black" is there again. If you would like to close this as a dupe, you may.
Thanks!
While playing right now I just happened to notice this (without the black, but the weird lighting issue) on a south facing wall on another structure. I have attached another picture. As I stated before, if this ticket is a dupe of another ticket please feel free to close it.
Thanks!
Edit: The area in the red has the weird lighting issue and the yellow marks the torches on the top of the wall.
