i had a crash with sand mining. it said something about not knowing what brown dirt was. sorry i didn't copy the words exactly. it happened right when the sand miner was finishing an area.
Name of the tile got changed in 0.16. Needs "dirt-dark" in control.lua changed to "dry-dirt" if anyone wants to fix it manually for now. Working on pushing up a small update to fix that tonight, but might be delayed a bit. Got some class work I need to get done.
