Contact list

When you first start the game, pretty much anyone that you interact with will go onto the contact list. As time goes on, that stops happening. When you meet someone new, you’re given the option to save the sim to your contact list. That option is especially useful when you go to parties. Saving the sim to the contact list allows you to interact with that sim later on. As for your question, yes, I had relationships with all the sims. I actually realized that I’m missing more than 3 sims on my contact list. So far, I noticed I’m missing about 5 sims but there could be more. As just mentioned, I’ve recently interacted with those sims. I even remember giving one of them stickers some time last week. What I don’t understand is why are the sims, who I have relationships with and just recently interacted with, are disappearing from my contact list. Meanwhile, there are sims who I have not interacted with since I first started the game in June, and who are also listed only as acquaintances, are still on my contact list. I would assume that the sims that I haven’t interacted with for a longer amount of time and have no relationship with, would disappear first rather than the sims I have relationships with and just interacted with within the last two weeks.
