Been testing the new 41 update and when I made a new game (no mods) I have found this bug. It only affects walls and windows indoors and seems to change color from green to blue to red seemingly at random. I don't have any idea of what might be causing this bug and have even reinstalled the game but it still hasn't fixed it. If anyone know what this is I would be grateful for some help in fixing it, Thanks
