I allowed room for them to open to right-angle.... is that not far enough? When you try to place it there's highlighted squares attached to the gate and they were on empty ground... apart from the fence of course [and I have tried with fence, without fence, with half wall, with full wall.]
I did get cheesed off with paparazzi earlier and walled the guy in... he just vanished as soon as my sim went to bed. I so do not understand why he found it so amusing and so happy while inside a small square of wall that was undecorated on the inside.. LOL so odd of him.
For now I've edited to make one side of the house exposed and moved the front door there. Hoping that'll hold them until I get this gate thing sorted.
