Part unlock via save editing (repairing a save)

[theend3r]

One of the old bugs from the version when the career mode was implemeted prevents me from unlocking ion engines, displaying them as unlocked in R&D but as locked in VAB. I never really cared about them untill now so I ignored it for this long but now with their newfound power I'd like to try them again. Would someone point me to the location in persistent file where the lock state variable is stored?

Thanks

Looking at my career persistence, I can see this:

		Tech
		{
			id = ionPropulsion
			state = Available
			part = ionEngine
			part = xenonTank
			part = xenonTankRadial
		}

So maybe try to make sure corresponding part of your persistence looks like that.

I found that too and mine looks exactly the same. It needs to be stored somewhere else as you can unlock some parts one by one and not only as a group.

EDIT: Unless it just adds "part = ionEngine" when you unlock it.

Then I'd take a look around the persistence if there isn't something else referring to ionEngine, perhaps blocking it from usage. Because this is the only reference to it in my whole save.

If it's a stock install, you can try to share your persistent.sfs, so we can play with it if you want.

If it's not stock, then it require a list of all the mods.

Looking at this thread, I guess there might be a different problem.

Jumbo-64 or Mainsail won’t unlock – [FIX]

The fix will depend on exactly how your game is broken, but try the following.

- Try and repurchase the parts in the R&D page

- Edit the engine and tank parts files. You're looking for the "TechRequired" line. It should say "TechRequired = heavierRocketry"

* Fuel tank is at KSP\GameData\Squad\Parts\FuelTank\fuelTank3-2

* Mainsail engine is at KSP\GameData\Squad\Parts\Engine\liquidEngine1-2

- Reinstall the parts files

1) Make sure you have a fresh download of 0.23.5

2) Delete the KSP\GameData\Squad\Parts folder

3) From your downloaded zip file, copy the GameData\Squad\Parts folder over to same parts folder you just deleted

(Might want to backup your save games in case you get overzealous.)

Maybe it is the same problem, just with a different part. Maybe when you upgraded your game, your ion engine did not get upgraded, or you're using a modded version with wrong/none tech level assigned?

If you go to KSP/GameData/Squad/Parts/Engine/ionEngine and open part.cfg file, you should see this setting in it:

TechRequired = ionPropulsion

Yeah, I probably know what's causing it now. When I update I copy all of my mods over the new version. It seems I'm copying some stock parts too. Thanks for your effort!
