TL;DRAllow ghosts to be placed on landfill ghosts so that you can place blueprints on lakes
What ?Ghosts (blueprint entities) should be placeable on water that has landfill ghosts on it. Robots shouldn't attempt to build them until the landfill has been placed, but the ghosts should be placeable there. Also, there should be an easy way to put landfill under every entity in a blueprint.
Why ?We can finally blueprint landfill, but there's still the issue that when I place a large blueprint with landfill on a lake, I have to do it twice: First to place the landfill and then, once the robots have filled the lake, I have to place another blueprint to build the actual factory.
Since there's no easy way to automatically detect when the robots have finished filling the lake, this can't be automated.
If blueprints could be placed on water with landfill ghosts, then I could blueprint the landfill and whatever I want to build on top in one go.
This could tremendously simplify building things on water, for example rail blueprints, nuclear reactors or water to train loading stations.
