I tried to find a problem when I tried to propulsion, although in theory the blue technology package can be done, but in practice it cannot be made, because you cannot make an internal combustion engine motor, its production cannot be done with a newly added assembly machine, only the original can be used. I use translation software to translate, which is not my native language, please forgive me if there is any inappropriateness.

Completely understandable on language barrier.

if you would like to provide your language I can translate it in the mod locale.

Thank you for reportingn. and most of them have been reported by other people and will be fixed in the next update 1.0.11

Hi, I am having issues progressing as I can't research "space Platform Thrusters."
There's a pre-tech that's missing, and when I look at the tech tree, it has it behind Processing units, Rocket fuel, and Electric engines.

But there's nothing to research after that, as it's hidden or something....so the main tech, the "space Platform Thrusters," tech is unavailable.

I am uncertain on why you are experiencing this problem, all of these pre-techs are available

prerequisites = { "space-science-pack", "automation-science-pack", "logistic-science-pack", "chemical-science-pack", "rocket-fuel", "electric-engine", "processing-unit" }

as I have a few hours in my night I will be releasing an update.
