Floor issue on top of customised stairs
@ceaufy Hello again! I've done quite a bit of arranging and rearranging but just could not get stairs to work within the current configuration of the building; just as you originally reported. I again believe that part of the problem is linked to an issue with the foundations, as well as walls getting in the way of the headroom. During my testing, I tried adding a platform to make a turned staircase and the game generated a bit of terrain on the ground floor above the platform so my test sim got a routing failure and wouldn't use the stairs. I tried deleting that floor and made a discovery that I think explains part of the issue.
There you can see how the game detects ground under the rooms even when the floor is deleted and the foundations are still there as well. This is probably the main issue for the stairs being deleted when walls are moved. I think it connects them for some reason. Unfortunately, I think that means you'll need to rethink the layout for this lot.
I came up with an idea for keeping a turned staircase without completely abandoning your original design. Click the spoiler if you're interested.
SpoilerBasically, I created a platform staircase and bumped out out the entry way, ground floor bathroom and the basement stairwell one tile toward the street. This will add enough room for your sims to access the basement. Make sure moveobjects is on so you don't lose any objects placed with it.
-Start with bumping out the basement stairwell one tile toward the front
-Add a platform in that corner, raise it up two clicks and extend it one tile toward the front
-Add stairs at the top and the bottom (I just copied the ground floor stairs for this). Make sure the green boxes are on top of the platform.
-Go to ground level, move the entry stairs to the side, then bump out the entry and bathroom one tile. After that, move the stairs back to the front.
For my final touches, I added a small room in front of the entry for a landing. Then I replaced the walls of the landing with fencing for a rail and placed the stairs on top of that. I added a half-hipped roof over the entry door.
Since the bathroom is bigger, I added a shower.
For the basement platform staircase, I added a dark wood to the platform.
Hope this helps!
