What did you do? Built a car on top of a placed blueprint, then drove it away
What happened? The ghosts were removed where the car was built
What did you expect to happen instead? The ghosts would be unaffected, because car is a moveable entity

Thanks for the report however I don't consider this to be a bug. Ghost are removed when a colliding entity is built on them. The fact it's a car doesn't really matter because nothing says the car will actually move.

There's a simple work-around: don't put the car on ghosts.
