Q: Why I can't copy, cut or remove ghost buildings with a deconstruction planner when the mod is active?
A: Because in order to stop robots from building mod changes ghost building's "force" (faction) to "neutral" and then changes back to "player" when you're done. You can't copy, cut or use deconstruction planner on "neutral" buildings.

Q: If I can't remove ghost buildings when the mod is active what do I do?
A: Right-click still works!
