So I had this for a while but now it's pretty annoying.
I'm playing at Westpoint,far west of the city in the cabin as you can see I extended the cabin by a little bit. Original size seen with the green border. Red is the extension But it doesn't really count as building,neither does the lighting match as. I thought it would be fixed by adding floors on top of it but that did nothing. As I had added two extra floors to it it still appears to be broken. I still get the same debuff as if I'm standing outside but without rain entering from above.
