So, I hope this isn’t me fucking something up, but it seems that the item “advanced seed drill” is useless atm, as installing the “advanced seed drill” vehicle part takes a normal seed drill.
Another fundamental issue: plows in general don’t seem to work right.
EDIT: In any case, I’m on it yet again. https://github.com/CleverRaven/Cataclysm-DDA/pull/13660
