@comicsforlife No, I don't use mods, and I will only use cheats to make the game more challenging. I think it happened on a save a few months ago and after Island Living. I believe a new pack came out and I restarted the save (I find that helps with potential glitches). Anyways, he was very high up in his career with a lot of maxed out skills. The abductions happened almost every night, but they stopped happening when I created a new save. My current sim is a copy fresh out of CAS that I started over with. I have not had any Alien Abductions in the same way, but I also haven't reached the same level of the career or met any aliens (that I know of because of disguises).
Right now, he does have many skills maxed out including logic and rocket science. I created him as a teen, so school projects gave him a head start with the rocket science skill.
Out of the whole experience, I just think the aliens wanted someone that could play good music for their parties because he had max Singing, Guitar, Violin, DJ, and Piano. He was also a B-lister at the time, so I generally found it funny. He never came home pregnant, thank Poseidon. I was already trying to raise a family at the time, and I was already dealing with the toddler struggles.
