I'm not so sure if this is a current bug or if I'm just simply missing something for required blocks on the grid holding the beacon on it to start building with the nanite factory. Other than a projector, power source and the beacon, is there anything else it needs to make it work and build the remote grid?

I've tried it even with antennas on both grids and verified ownership, but no luck. Everything had sufficient power to do it since I was using a flashpoint reactor from the hydrogen mod for over 1GW on the factory's grid and a large uranium reactor powering the remote projection grid.
