I think you are aware of this bug, but I will have to insist on this one because is very annoying.
Solid Fuel Thruster and Solid Fuel Oxidizer are not receiving any oxylite after they come back from space mission, I have to restart the game all the time. Worst part is that Oxylite gets deleted, for me with 3 polluted oxygen vents I can afford losing some of my oxygen but its a really bad bug.
The other bug with rockets its visual, when rocket is in space you get half of the rocket art or on launching sometimes the bars of liquid storages remain there.
Please fix first bug
But thats all the bugs rockets have for me in few runs.
EDIT: Forgot to mention, iron have no problem to get refueld on solid fuel thruster
Steps to Reproduce
Not clear when first bug starts occuring. It might be reloading the game with a rocket in space. It didn't appeared before first open/close the game, it worked fine.
