I had only had 1 abduction since playing and that was years ago. Ever since the 11/7 patch, my sims started getting abducted frequently. I had a sim visiting another one of my played households and 2 of them were attempted abductions, I reset them. Then they took another when I wasn’t paying attention. I didn’t know npcs could get abducted. So I left and went back to my home lot. My sim was immediately under the light on the side walk. I reset him so he didn’t get taken and sent him to bed. He woke up 2 sim hrs later going back to the strange light. My sim didn’t even know any aliens, but I spent the next hour deleting every alien in the world.
I wish we could turn off aliens in the world unless you want that specific gameplay. My current save has like 6, and no one is in the science career. I delete them and the game spawns more.
