Couple of questions for a returning player

Loved whacking day too and the Stonecutters unfortunately I doubt we'll ever see the like of those again, as to the donut producing buildings chances are they'll return at some point as they have already been available more than once, one building to watch for is Golden Goose Realty as at some point you need it to get land tokens to unlock quite a large area of land in the game as the cash purchasable land is limited and the only way to expand is via land tokens but the building only appears appears for sale rarely.
