[Eighty Swords]

The "bottom" corner that points toward you when you're looking at it looks like two pieces of fence because of the way the items are made to display. Build a custom house and you'll see what I mean. It's not actually "two pieces" of fence, it's just a single piece that blocks that one tile. You could use a one-piece fence and get the same effect, only it would look like there's a hole when there isn't.

The top corner is actually just a single rod that takes up one tile also. The fences LOOK like they come together at a point, but there is a single tile missing. You can find places like this in the world also since it's an easy thing to miss.

... just like what I said...

And as far as "tough luck" for people whose houses are too close together, I think you missed my point. It's not that they won't be able to have fences, it's that their two house zones would overlap. I could technically be a douchebag and lock down stuff in someone else's house from my own so they can't pick it up anymore, and I'm sure it would cause other problems in the overlap zone.

I wasn't talking about overlapping zones IN the house, I actually never thought about that part but I'm sure there's some way to fix it so if the zone would touch a wall or foundation not belonging to the house that zone is for then the zone stops there so it doesnt creep into someone else's house.

I was more so talking about the area around the house. Big deal, so you dont have a fence all around your house because someone else was there first, put the fence infront of your house and move on with your life. Like someone else suggested though, this could just be done so it's only to the front of your house you can put it. Or if it's such an issue, I'm sure GMs could move the houses 3-4 tiles away from each other making 6-8 spaces between houses so the fences don't even touch and there can be fences all the way around both houses.
