Wood dock pathing issue?

[Vrayna]

Make sure your dock piece is correctly connected to the land. Sometimes people are able to reach odd spot, but if there's something in the way when they want to go back hoe, they'll just stay where they are. You can try adding one piece of dock to go further inland or try to build a rod right to the edge of the dock. If there's one square that can't have a road, it's likel causing the issue. Either flatten it with the flatten tool, or add a dock piece.
It could also be one of your houses having an issue. Make sure you haven't blocked the way into houses with the pathing tool
