There seems to be an issue with villagers finding their way into houses to get to their stations. I started a new world and began working with a Taiga village. I built several houses to add jobs that were not already in the village. Several villagers are doing fine, but I have a couple that seem to be confused about how to get to their stations. They keep trying to approach the stations through the wall that the station is against. They won't go to the front of the house and enter through the door. After a while of being unable to reach the station, they just begin wandering aimlessly. These particular villagers also will not socialize at the bell. I'd been working on a Plains village the week before and did not have these issues.
