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

Tanks were the main issues.

Not entirely related, but I was also unable to deploy maraxsis submarines properly on Maraxsis, but they could be deployed on Vulcanus, so its not respecting surface construction conditions.

Probably should be a seperate issue entirely, but there's been a lot of weirdness with the deploy UI, especially regarding equipment. Sometimes it will deploy a blank spidertron despite having selected a equipped one, and you don't seem to be able to properly navigate back up out of the equipment menu.

Ok im not having an issue with nuclear / rocket fuel deployment

Tanks seem to reliably detect and deploy with the fuels

For the maraxsis issue, I have to insert some logic that only allows maraxsis submarines to deploy to maraxsis' main surface and not anywhere else
