Making a building that I needed to sink the wall a single voxel. I found that they have no problem building the posts like this, but won’t build the wall itself.
Upon removing voxels beside wall, the wall becomes built.
So to recreate this:
- Use the super secret “n” hotkey to dig single voxel trench.
- Freehand a wall in said trench.
- Wait while nothing gets built.
