Hey, I'm having an issue where all of the aircraft are unable to be fueled be Rocket Fuel or Nuclear Fuel. The highest tier of burnable fuel available to be used is Solid Fuel. I think it might have something to do with Planet Maraxsis and how they changed values for using barreled oil as fuel in the submarines, but I'm no coder. Other vanilla vehicles (car, tank) are still able to use those fuels. Please let me know if there is any further info I can provide to help resolve this.

I happen to be playing with Maraxsis, so I was immediately able to check if this is an issue, and yes, I see the issue you're describing. I'll look into why this is the case. Thank you for letting me know.

This bug has been resolved on both Aircraft's and Maraxsis' ends.
