Sims 4 Second Floor Disappeared

I m building a house in brindleton bay on the 64x64 lot in a fresh blank save.
Sims 4 second floor disappeared. I built a tiered house with roofs on the second and third tier. I am having this issue now. The issue i have is the second floor starts glitching disappearing and i can t do anything with it if i build a building at the back of the lot. I ll try to place a floor tile and it ll basically just ignore it s existence.
I think the game isn t recognizing it as a member of the grid honestly based on how it s acting. Replacing the furniture only disappeared after i left and returned to apartment. Trying to make a second floor and it s not working. The house lavishly from all packs and finishing the garden i started.
I ve created a community lot and when i placed in a lot some objects from the ground floor dissapear. It only happens in the ground floor and only dissapear some objects from one part of room the objects from the oppsite side stay in their place. There you can choose between cas and objects. Hit page up on your keyboard to move up to the second floor view then build the walls floors etc from there.
Do you know what happens. Cas has the option update cas cc for pets patch. If you have sims 4 studio you can go to content management and there s a field titled batch fixes. Objects has the option fix objects for cats dogs patch.
I repair the game origin sims 4 repair and still happens the same. I originally started on the 64x64 lot in del sol valley. It edits the first floor not the second. I can place windows on the first level but they disappear when i place them on the second and third levels.
The sims 4 help center can now be found here.
