I haven't moved the admin boundary. I just removed two clusters of about 10 overlaying plots points within the boundary line. 

The walls in these areas are continuous, albeit in disrepair, and to pass through them you are actually walking on the remains of the wall foundations. I wasn't sure how to describe this on the map, and used the stile descriptor as it seemed closest to what is there.

Not sure about "gate" between fields. Again, wall here is badly damaged and stone robbed out. I'll take another look there soon and see if I can put in something more appropriate. In meantime, feel free to amend.
