The nuke issue should be solved in v 1.0.4.
The fuel issue is strange however. Krastorios rocket-fuel is identical to the vanilla rocket-fuel, the only difference is the fuel value (Krastorio: 20 MJ, vanilla: 100 MJ). I am correcting this in v 1.0.3, but even if not 20 MJ should still be far enough burn value for the drones.
Does the Krastorio rocket-fuel work in the regular aircrafts? How far can you fly with a gunship and 1 rocket-fuel?
I think Krastorio changes something regarding the engines (in modding terms: the burners) of vehicles, this might cause the problem. But I need more time to investigate this...
