Locked out
Edit2: SOLVED. The house now has two side entrances. Lucky it has walls outside the fence.
So I moved my couple with baby to this house. Baby is sleeping in bed, dad is doing who knows what, mom just bought a dog and is playing outside. But it's a small house on a beach lot so I wanted to give them access to the back part. Oh, maybe let's move this little gate from the front to the back. I'll put it in my inventory and there'll just be an opening in the front, great! Nope, the gate is part of the patio border, border is now closed, and I cannot place the gate back because I have to be level 15 for that (and finish some quest, I'm level 12). Whoops, so now baby and dad are inside, mum is outside, and I can't put the gate back. Help! How do I solve this?
Edit: dude was planting tomatoes in the community garden, so I can't even pick up the baby and move them out.
