Frustration

Hey everyone, this may come off as stupid but it’s driving me up a wall. I decided to flatten my island and along with that came flattening my little tiered neighborhood. I realized shortly after that for some reason I literally can NOT recreate what I originally had. Has anyone else ever run into this problem? This is my literal 6th time trying to recreate it. I’ll post what I had. If anyone can help me out let me know 🤣 I’ll post pictures…otherwise, thank you for letting me vent.
