Wall Corner bug
I'm having an issue where if I put wall patterns on corners like the one in this picture using the wall sidings Simple Siding or Clapboard Crush, it doesn't put a corner thing there.
This behavior is by design. Siding styles with edges were programmed to auto-determine which wall tiles to place the edgings on. They do not work on inner corners at all. When it comes to outer corners, the wall must be at least two tiles long (i.e. it won't work for a 1x1), and at least 2 tiles away from another connecting wall in order to show the edging. It would certainly preferable if we had manual control over the edges, and we have requested this in our Build Mode Feedback thread, but the way it works currently is not a bug.
