Hello, not sure if this is the right thread to ask this but I didn't found another that seemed fit better.
Anyway; I'm currently in a career game and going to try to shoot beyond LEO. To do so I researched some better avionics to save battery and weight. I'm now at "Early avionics and probes" unlocke and researched.
This should let me select the "Early avionics" configuration in the VAB, which I can; but when I send the craft to building list the popup window appears and tells me I must unlock it for 4000$.
No problem, I have plenty of funds! But then I click and nothing appens, no founds deducted and no avionic unlocked. I can use any level up to my tech node for the Science-core, but Near-Earth avionic is stucked on Start level
This is my tech tree and what I see in the VAB: https://imgur.com/a/hcnZQkE
I played previous versions of RO and don't remember having this kind of problem, but had a long iatus from the game and my memory faded.
Anyone knows what may caused it, how to solve it or at least how to edit my save file to make it unlocked?
