Hi,
Recently while fumbling around with my island design I stumbled upon this interesting exploit that (with an auto-clicker) would allow players to farm infinite money.
I assume that it works only with refunds on. I provided a screenshot of it below this paragraph. You have to click repeatedly on the road marked in white and the game will refund you with 2 coins but won't destroy the road piece. Which makes it possible to farm money with an auto-clicker (or just sheer patience and dedication of manual clicking I guess).
Here's a link to an imgur gallery explaining how to reproduce the effect with images: https://imgur.com/a/jxib8iu
I have no clue as to what would cause it. I'm playing without mods and on the game update 11 and since I haven't seen anything in the game update 12 about fixing a bug with bridges I decided that I might just as well report it
