@koshion220 Okay, I'm glad that worked for you. Sometimes a database rebuild in safe mode helps with some stuck on load screen issues. If your drive was very full though, that also can cause trouble.
My first save on PS4 had a huge house and a huge lot in brindleton bay, and I could barely play them. The stuttering and lag was so bad. I even submitted that save to QA.
I've gone back to that save and moved them to a small house with next to no packs present in the build and all the weird time shifts and lag has disappeared. The micro stuttering is still a thing, even on PS5. Actually, all my builds use very little packs and I avoid the large lots. It is a bummer to use these restrictions but it does help keep the gameplay struggles to a minimum, barring the actual bugs.
I definitely understand the frustration of not being able to load and play your families.
