@DarkDiamondSimsAny platforms in your build? (Or in a previous build on that lot? Even just using the platform arrows instead of the foundation arrow?)
No, this was built before platforms was available and it was placed in a brand new world.
Yes, I have taken out my mods, but I get the same results. However, I have noticed something peculiar. When I build the lot in Newcrest, I get the issues with the stairs, but when I build in Willowcreek, I get stairs. (I was wrong when I thought I was in WIllowcreek the first time. Sorry.) I built the house on two different lots in Newcrest and get the same results, but when I went into my Sandbox save (where I just build lots where the original lot was built in WIllowcreek) and the stairs work just fine.
The lot is already on the gallery. It's called The Goliath Townhouses. 🙂
