Pet Adoption Doesn't Work

I had the same problem. The adoption person walked in my front door and through my house then waited outside my back door and would not come in. In the process of checking if my doors were locked I found that my front door wasn't actually The Front Door. I clicked it and set it to be the actual front door and called for the adoption again and it worked like a charm. If you have this problem it's possible that it has something to do with your door setups - check them. Mine were wrong. This could explain why it works for some when they adopt in to a different home then their main characters house.

Detailed description:
My problem occurred in the stock 2 story Spanish house in Oasis Springs on the 40x30 lot. They (Origin) have messed up the doors on this house. Click your front door and set it to be the proper front door and problem goes away. Good luck!
