It's sometimes impossible to find favorite cc pieces. Sometimes though it helps to know friends that are more familiar with CC than you to help you find those pieces. lol
In that same save that I was having problems with my consignment shop, aliens abducted my male Sim. I was surprised, actually. That had been the first time it happened since I enabled Seasons again. I looked up a mod to stop abductions and now testing it to see if it works.
The alien abductions are few and far between from what I understand, so it may take a bit to see if the mod works.
I've read where if you're trying to Avoid the Noid, err... I mean alien abductions is to not use the telescope either at all or at night, not sure which or if it's both. Get rid of space rocks if you have any. And uhm.... Don't stay up all hours of the night. lol *Blush*
More info on Aliens and avoiding them:
It's rare to have an Alien spawn without triggering it. Using the telescope, having high logic and meteor stones on your lot increase your chances. Otherwise its super rare. And your sim will never be impregnated without these circumstances. They will just visit outside your lot late at night and then leave if you don't interact with them. They wont move into town or anything.
