This mod changes the way you interact with ghosts. You can no longer place a building over a ghost of a different building, which makes blueprints easier to plonk down without construction bots
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.

Most of the time, objects will still get placed down, but every so often, it seems that an object's ghost will disappear, and the item in the inventory doesn't get placed.
