Fuel tank bug

[Fortochkin]

Hello, I haven’t started the game for a long time, but already at the beginning of the game I’m studying the very first technologies for fuel and engines, for example, “rocket science fundamentals”, I’m buying (developing) all the details, and when I switch to the assembly shop, the fuel tank is as if not bought again, and a copy of the old tank appears in the scientific department, and the development must be paid again, and so on ad infinitum. As a result, I can’t fly on anything other than solid fuel engines

Hmm... depending on your game settings, if they are like mine, you need not only to research a particular node but also have make a one-time purchase of the respective parts.

When you buy the parts, do you have to buy them over and over again, i.e. a part isn't available in the VAB or SPH after purchasing it? If yes, I'd assume something is wrong with your KSP installation, a Steam file verification might help.

Yes, I should buy them over and over again, these parts are not available in the vab, as if not developed. Steam file verification was done, and nothing new

That's pretty weird, never seen this myself or heard about this exact issue. I do have (say after a mod update) to purchase parts again I did purchase earlier, but having to buy the very same part over and over again, to no effect? No.

I assume something is wrong with your KSP installation.

What happens if you change if the entry costs setting as described here?

I see four non-stock parts in that tech tree node, do you have any mods installed and if so what are they? One of those could be to blame.

I did as it was written, now it is possible to use fuel tanks, however, in the research center several models of old tanks are now added for one call to VAB

These are copies of the old FL-T100, which cannot be repainted. These tanks are cloned after each call to VAB. Of the mods, I used MechJeb and ModuleManager, but such a problem also exists with completely disabled mods.

 

At the moment, I deleted the game and the folder with the game, and I download from Steam again, after half an hour I will say whether the problem remained after reinstalling the game

After a complete reinstall, the problem is gone, thank you very much
