Apologies, Itch.io's spam filter ate your post and it doesn't notify me when that happens - I've added new autonomy tests on memory erase (and also on my new mind wipe interaction) that will prevent aliens and alien hybrids from autonomously memory erasing their friends and family members.
You can still get autonomously memory erased, but its more of a self-defense measure now. It'll trigger if you're an enemy of the alien and have discovered their identity, or if you've made them very, very angry.
If your sim has the trait_isAlienPollinator trait, then the Pollination Technician career should be visible in the career panel when your teen reaches adulthood.
