Thanks for the response, we can definitely live with that rule. Looks like the only way to remove a highwayman, and possibly steal the road would be with a builder second turn if you are lucky enough to extend your builder’s feature in the same turn, then draw a second tile that does extend the road you just vacated!
PS: By the way, the other Fan Expansion we are working on is your Flying Machines 2!
We are printing the tiles on full size sheets of Sticker Project Paper, then pasting them on Carcassonne blank tiles direct from Germany. Only problem so far is how to get the edges of the tiles not to have the white strips from the blank tiles. We don’t want them to be noticeable when we draw random tiles from stacks of tiles.
