My kids have become a bit anti-social lately and are all making their child-friends for Social Butterfly online.
Playtime Captain counts 3 fiends even among siblings, even retroactively, and Successful Lineage counts the child's 3 friends of any age, also retroactively.
But Social Butterfly requires the aspiration's milestone for 3 child friends to be selected when the friends are made.
Try chatting online with your next child(ren) and see if that fixes your bug. It's quicker than cloud/start-gazign, although not actually "social," LOL!
Haha, you've done a great job, Watcher, of turning Cassia into quite an obnoxious mother.
She might as well have the Hates Children trait in view of how she treats poorTh Dorothy, prevented from aging up and living her own life by her mother's collections.
Regarding the MySims trophies, I recommend going to the Flea Market to "Trade Collectibles."
Cassia can repeatedly trade MySims trophies as long as she's got one in her inventory. I don't recall whether children can also trade.
I once completed 3 different collections during on Sunday at the Flea Market.
Please try it, haha! Cassia's so very close to completing her collections now.
Oh, the best source of Time Capsules is the Scientist's Lab, especially when you're trying to complete a different collection. (Grrr?)
Dorothy is so accomplished and Cassia is close to done with all her requirements! Go Watcher!
