I’m taking the blame for that, even though the mapdata thing was KA101’s addition.
That lean-to has caused no end of annoying problems since I first thought it up, before I ever PR’d the mod. ._.
I originally wanted to simply mod in an option to turn an existing pine tree into an improvised shelter, but that would be illogical because then it would break into a shallow pit that technically hadn’t been dug out. That would be annoyance number 1.
Annoyance number 2: it was the reason I worked on a variant tileset in the first place, because of transparency issues when using another tileset’s fallback tiles.
It only gets derpier the deeper you go. ;w;
