If I placed down a foundation, I would expect to be able to move it for free before any builder starts working on it
Sometimes you place a building and realize you made a mistake, right now it's kind of tedious if you have to delete it just to move it over a cell, or similar.
Adding onto this:
Moving Houses and Farms costs resources even if you have the Levitating Monument modifier (allows most buildings, not just the usual ones, to be moved, and at no cost). It's weird that now you can fling your Central Storage across the map for free but moving your farms still costs 1 Plank.
