Items Keep Disappearing

I'm currently having an issue in my game where items both on my Sims' home lot and other community lots are disappearing from those lots. Like, I'll leave a lot, especially my Sims' home lot and I'll return later to find that some of their furniture or objects are gone and I'm forced to replace them. I tried checking household inventory but the objects weren't in there. I tried leaving the lot and coming back, that also didn't return the items. I don't know if it's a mod issue because I do use mods or if it's just an issue with the game itself because I did just get Adventure Awaits. This really needs to be looked into in my opinion because it's a real issue to have to constantly be replacing items you already bought for your Sims' homes and the community lots missing items is an issue too because you can't use the items if they aren't there, obviously. Playing right now and having this issue. Frustrating.
