Ah, ok! For now, I've just used MCCC to disable the autonomy of telling others about aliens (which, since i play on Long lifespans would have probably resulted in EVERYONE knowing anyway) which has gotten rid of the message.
since i am here, i have another issue. As mentioned i play on long and use MCCC, which I have used to increase pregnancy length to better fit a long lifespan. I hate the pregnancy walk. If i just had to put up with it for 2 days, not a huge deal, but I'm going to have to deal with it for like 2 weeks. I would like to use a mod to disable that walkstyle, but this mod seems to conflict with every mod i've tried to disable the pregnancy walkstyle, and while the walkstyle is disabled for normal pregnancies, for abduction pregnancies, they still do the default walk. would it be possible to make an optional version with the walkstyle disabled? or use the vanilla pregnancy settings (at least as far as physical/walkstyle is concerned) so other pregnancy mods will work?
*edit - ok nevermind, i opened it in Sims4Studio and found where to disable the walkstyle
