Hey there Watabou. I haven't used the generator for a few months so not sure if this is a known issue. Seeing some road "oddities".
The image linked below shows what I mean. (1) Road from a dock to a house but not to any main roads. (2) Row of houses without any road/path at all. https://imgur.com/a/sA8nvIb
I'd also like to make a suggestion that all docks connect to a road or path (or maybe just an option to do so). docks would be well used so there would naturally be a worn path to them.
(Btw is there a place to report/request stuff rather than clutter up your comments? Or do you prefer it here?)
