Summary: After building block wall structure, and then attempting to create a road on top of it hearthlings built the road without destroying the previously placed blocks. This resulted in two blocks occupying the same space.
Steps to reproduce:
- Mine out a block from the ground.
- Place a slab to occupy the empty space.
- Build a road or foundation over the area you constructed the slab.
I expected the hearthlings to mine out the structure and then place the road.
They got lazy and just built the road in the same block as the structure.
After testing it myself I saw that this occurred with previously placed foundation, slab, or road when building foundation or road on top of it, and you can have seemingly infinite amounts of blocks occupying the same space. I tested up to four.
