You can't use solid fuel thruster before research of oxidizer tank, which requires 400 science points AND solid fuel thruster to reach 20km range to get this points from distant satellite
ok, oxylite can be delivered manually even it isnt requested by tank (it requests 'Iron' but no oxylite) and there is no indication how much required
BUT after rocket is landed, tank is still full , nothing is consumed during flight
I rebuilt rocket with petroleum engine and cargo bay, filled tank with petroleum and now i stucked with 0km range
Steps to Reproduce
1 research solid fuel thruster and cargo (200+200 points) 2 build rocket with solid fuel thruster 3 build rocket with petrolium engine and fuel tank ... not enough points to research next technology
