Foundation Over Lowered Terrain Disappears
So I am on PC, and I am trying to build a castle with several decorative moats. I do not have mods, nor have I ever used them. I recently cleaned my computer (cookies, cache, etc). I even went in and deleted cache and the others in the Sims 4 folders itself (Sims was running heavy and I could not figure out why, so I did a cleanse). This issue began about a week ago.
So far, I have not added water. I have the terrain built and the general outlines of buildings created. I have walkways created. The terrain is lowered to 1 basement level down, with two floors below (but not under the moat areas)
However, when I go to fence in the walkways, closing the fence creates a floor. Upon deleting the floor, the foundations vanish.
I have tried rebuilding sections at a time to no avail. I cannot get the foundation to reappear. I have even scrapped the project and started over. This is my third attempt to create this.
Any help out there?
I had it level with the terrain. I eventually discovered that I had to raise the platform by 1. It was an issue with stilt foundation. I'm not sure -why- I needed to raise the level up by one, but it worked. But I am definitely MagpieMorrigan. Now if I could just get the friezes to stay or snap into the correct spots or stop disappearing every time I place a furniture item... but at least the platforms and foundations work. It's down to just the interior now. Thank you for the assist.
