[0.16.28]Landmines shown by blueprint over ghost over mine

[Bilka]

Enemy land mines are usually invisible. When placing a ghost over them, they are also invisible. However, when holding a blueprint or when trying to shift place an entity over that ghost, it is possible to see the collision outlines of the mines. This works with any entity.

Thanks for the report.
Fixed for 0.16.29
