I had a 2 block wide dirt road near my homestead, I wanted to sponsor making it wider and making it into a stone road. But 'road' contract for some reason only permits working with my own property trough construction signs, not public one. Road only passes my property, I do not own any part of it. Road did eventually get updated, but I would have preferred if it got expanded earlier and if turn to my house got a bit wider.
Suggestions:
Roads are 'public' property, so permit sponsoring roads in a public manner, by just specifying chunks. Ideally it should be able to assign a pay per blocks placed.
