@SimQARobo I was playing with the Wakefield save again tonight and I returned to the household that I had problems with before. The pregnant sim had his baby so I tried to adopt a dog again, also knowing I'd been successful with another household in this save, as I reported previously. I had one of the other members make the call and trigger the adoption. It took the money, told me I was adopting, let me name the dog and then the dog didn't get added to my family. The option to adopt was still there so I tried 2 or 3 more times, and each time it did the same thing; told me I was adopting, took the money, and gave me the option to name. After the third or fourth attempt I put cheats on to see if I could just add the dog to my family using cheats and I didn't see that option. I decided to try and travel with the dog (and the rest of the family excluding the alien baby, who is part of the household but of course had to stay at home) to see if that did anything and when I got to their destination (I chose a community lot, specifically Willow Creek Park), the dog was with them and was also part of the family. I did notice that 3 of my sims already had a relationship with the dog and the fourth sim, the one who had been pregnant the first time I tried to adopt, had to introduce himself to the dog. I then took them back home where I noticed that the sim who had to introduce himself to the dog didn't have the ability to train the dog but the other three sims in the house did have that option. Not sure if that helps, but I just thought I'd mention it as I thought that seemed a bit strange. I did save right after they returned home; not sure if the save would be of any help.
Thanks and regards,
Jennifer
