Cannot place stone column.

[DreamingVoid]

In the corner of stone windows, from the inside it is impossible to place in the corner. Snaps to the other 3 edges of the foundation, instead. Allows placement when outside the structure.

Virtually everything except foundations is slightly less finicky than this.

Terrible building system. You can be looking right at something, and it snaps to the wall next to you. It's absurdly bad. To place a wall, you can't even be 1 foundation away.

Why you even worrying about building on a demo? lol
