I've talked to a lot of people and nobody can figure out why I can't put a gate between these posts. The first pic is when I encountered the error. Then the second pic is my attempt to "work around" it I tried extending in a bit and yet still cannot actually build a gate. Some interesting facts:
*The wall already has gates in other areas
*I am allowed to build 2 wall segments to "close it up" but just not allowed to gate it
*The paving stone cannot be destroyed which was what I thought was the original culprit.
50 Silver in boston to the first person who can figure it out .
