It seems that when using hoder’s tileset in experimental builds the tile used for things lacking their own is a zombie. In 0.A it was a magenta circle. Was this change intentional? Is there a way to change it back to how it was in 0.A?
I’m not sure but yeah, sounds like a bug to me. An obvious “No Tile Available” tile is the correct answer to not having a tile, not substituting some other tile that may be completely unrelated to the actual thing that needs represented.
That said, this is pretty much a bug report (thanks for reporting). Gonna flag it for move to the Garage.
