When two seperate robot networks have overlapping construction areas, then entity ghosts built in the overlapping area trigger "missing construction material" alert if one network is missing material. Even if the other network has already dispatched a construction robot.
- Load the savegame.
- Place the assembling-machine-2 ghost from your hand onto the hazard concrete.
- See the alert while a robot from the right network is coming to build.
(Call it wontfix or minor if you want, but don't NaB-bullshit me again please. )
