Disappearing Sims

No, not really. Sometimes my Sim will disappear for a moment, but they never exit the family panel of icons. Do you use mods? I do, and have attributed this strange phenomenon to a mod.

I use mods but they are more Cas and build mods more then game changing mods I haven't used any cash or build mods in this household though and the mods I used in other household never disappeared. I notice was a household I don't play it's a premade household the karaoke legends one of them disappeared so I played it off like they moved. The second was I was actually and the child disappeared from the game I'm like wait....what!!!! I got them back though I just can't see their needs now.

@Briana2425 Do you mean your Sims randomly disappear off screen (with or without a plumbob remaining to show you where they're supposed to be, and there's an empty space where they should be listed at the bottom of the screen, but they still show up in the family tree? If so, or if that sounds close, then I've had that as well and its a bug that is listed as being fixed.

They disappear from the house, they disappear from the household when you click on the family to play. They were literally I had to call them back invite them over and add them back to the family.

I've noticed relationships getting culled from the friendship panel and my sims having to "re-introduce" themself to friends but their friendship is still there from before.
