When I place a ghost of a Factory Building Mk1 and allow the drones to place it, I get an error along the lines of, "ERROR: Unbound factory building: factory-1@nauvis(191,12)". Reproducing the error is consistent, and I'm using the current versions of both Factorissimo2 and Construction Drones. The error does not resolve after allowing time (and further ticks) to pass -- once a factory is placed by a drone, it's broken until deconstructed and placed by another method. I do not get this error when placing the factory by hand, using built-in construction robots, atomic bots from AtomicRobotsFixv 1.0.0, nor Nanobots, so I don't think this is a problem in Factorissimo.
Is there an update step of some kind being missed by the construction bots? I wind up having to dump my drones into a wooden box if I need to build out a blueprint with a Factorissimo building.
Great mod! Thanks!
