Product: The Sims 4
Platform:Mac
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.65.70.1220
What expansions, game packs, and stuff packs do you have installed? All.
Steps: How can we find the bug ourselves? Build a regular room and a basement underneath. Raise the foundation. Create fenced-off room inside the ground floor room and remove the floor, then remove the basement ceiling to make the area open to the basement. Try placing stairs to the ground floor (or ladder) within the fenced off area so the top of them leads to the ground floor.
What happens when the bug occurs? The error message "Incompatible with Terrain Constraint Block" appears and the stairs can't be placed. Also, while the foundation appears intact from the outside, it's invisible/see-through from the inside.
What do you expect to see? The stairs to connect the basement with the ground floor. And the foundation to be solid.
Have you installed any customization with the game, e.g. Custom Content or Mods? Never used.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure
Adding pics of the issue:
I have an open space into the basement, which required not only removed floor of the fenced off area but also removed basement ceiling. While the ground floor is level with terrain, I can place stairs from the basement leading up to it (as well as a ladder). On the right you can see stairs placed with no open area.
When I raise the foundation:
The ladder works fine, the stairs on the right work fine, but the stairs within the open area get deleted and cannot be placed again.
This happens in all the area, not just next to the outside wall.
Also, with the foundation up, on the outside wall it disappears when the area is fenced off as below.
I have tried this with multiple foundations, even flat ones that shouldn't be in the way of the stairs. The ladder works as expected but the stairs do not.
I took a look at this in a test build and got the same thing to happen. The error I got when I tried placing the stairs was Incompatible with Terrain Constraint Block. Ladders worked fine but stairs wouldn't. So I agree with you that it is either a bug or a design oversight since it does work if the first level is flat to the ground. It should work if the foundation is raised too.
What I found really odd was that I could place a stair from the basement that ran through the hole in the floor to the 2nd level above the basement but not from the basement to the 1st level. So I can build a 2 story stair but not a 1 story stair from the basement.
Hope this helps.
