Is it still impossible to break down a single tile of wall without leaving rubble everywhere? I know the jackhammer breaks down walls but it also breaks down nearby walls and creates unclearable piles of rubble. What about the pickaxe? I suspect it’s the same as the jackhammer, but you never know.
I’m trying to modify my newly found Public works with some new doors and walls. If it’s still impossible I guess I’ll just debug a hole in the wall to build a door or stationary utility vehicle in.
