Unable to place crude plank anywhere that makes sense

Heyo. When the additional crude tileset pieces were first added, I played with them a bit in PTR and made a nice "rug" at the front door with it placed just inside the door over the existing stave upper floor. I also was able to place it outside on the bare ground to act as a "welcome mat" at the foot of the stairs.

Since the latest update, I haven't been able to place it anywhere that makes sense. I've tried inside on the floor like I did in PTR previously. It stayed red no matter where and how I spun it or raised it. I tried it outside as well, but no luck. Just now I thought to try it near an outdoor ttier 1 campfire that I was trying to build around and dry out, but it stayed red...until I placed it randomly halfway over the fire. That...was weird. I tried to use the R key to raise and lower it, but it only raised one click and turned red. No luck there.

The whole reason I was trying to place it was to test another bug I found where an awning built over the campfire didn't protect it from the elements.
