As the title says, after I built a city bridge to an island the villagers appear to continue walking "along the bridge" for some distance even when the bridge ends/goes underground. This is not present on the other end of the bridge. Even though its not an issue for me this time I can see it becoming a problem for others as the behaviour is unexpected. The expected behaviour would be that they can go right/left right after the bridge ends visibly. In my case the villagers/builders needed to go down to the shore/beach to build on a Manor House in the water.
I guess that this is a low prio bug/quirk, so let me know if you'd still like me to upload the save file.
