Engine build error

**Title:Vanishing buildings

I’m trying to level out steps using slabs to create steps one step at a time. it all goes well until I have them even and try to build a wall across 2 different buildings, then the wall vanishes, and if I hit to complete, the previous building vanishes (what was already built):**

Steps to reproduce:

  1. Build buildings right next to each other
  2. level out the areas between them with slabs.
  3. try to build across the slabs.
  4. I don’t know if this always happens
