[R293 (x64)] Erasing Built and Non Built Slabs At Same Time Causes Error

Building up something off of a pre-built structure, and went to erase the top layer, which crossed the center pillar that was already built. Error ensued.

So to recreate this:

  1. Build something using slab tool.
  2. Finish it (complete build).
  3. Build something off of it.
  4. Erase new building crossing part of the previous already built building.
