I'm trying a simple vessel with 364 parts, 301.25 Electric Charge, 18 Liquid Fuel and 22 Oxidizer.
In orbit I have a small station with no production, however I've docked a tanker with 45000 rocket parts, 13616 electric charge, 4455 liquid fuel and 5445 oxidizer... Nothing happens...
Landed I have a ffacility with 4 drils working, 1 conerter transforming Ore into metal and 1 lab transforming metal into rocket parts.
Even have enough resources, the build doesn't start...
