Despite having both rocket and Nuclear fuel in the space platform, it was not detected or deployed. Its possible its a mod issue modifying those fuels, but it should probably be able to use a less rigid way of detecting fuel types.

Unrelated, but a confirmation that a launch is successful would be nice. And the button to return to the deploy menu from the inventory grid doesn't seem to work.

which vehicles are you deploying and not seeing rocket fuels? (im not having this issue in the unreleased update, so its either fixed now, or specific to your modpack)

noted on the second point, will add in the next release
