Also a bug, there is an odd mirror reflection effect going on with the chimney of the forge. When ever you move ingots around the forge you can see their reflection on the stone wall of the chimney, now I'm no rocket scientist but I don't think rock is supposed to reflect things haha.
I just noticed it now though and I've been playing for 4 hours in just the past few days so It doesn't stick out very much if it was to be pushed of to patch later.
