Duplicate items in tech tree. Can't use certain items.

[MusicMetalHead]

When I try to launch vehicles using certain, parts the game tells me I don't have that part researched yet, even though I do have the node unlocked in the tech tree. When I look in the tech tree I see multiple duplicates of the same item. How do I fix this?

 

It would only let me insert one photo so here's a link to the other one

An example of the parts you're talking about would help greatly. Thank you for posting the screenshot, as this always helps but in this case, it is necessary to now what part or parts the game says you do not have

Both the MK1 and MK1 inline cockpit do this as shown above. They are the only parts so far.

Edit: The MK1 cockpit works but still shows duplicates in the tech tree. The MK1 inline cockpit must have gotten moved to a different branch of the tech tree in an update because it appears later in a node I have yet to unlock, but still shows loads of copies in a previous unlocked node. After restarting KSP the MK1 inline cockpit is no longer available for selection. I never accepted any contracts that involved testing it.

@MusicMetalHead: if you had a part showing multiple times both in the tech tree and the editor, I would sure point at multiple config files for the same part being loaded. Don't really know if multiple parts only show in the tech tree. It would mightly help to see what KSP does during initial load, when opening the tech tree and the editor for those parts; but we need to read a log file (output_log.txt or player.log depending on your OS, more info here). Best also to provide all the other info as suggested in that linked thread. Of course, as you posted in the unmodded section, I start from the idea you are running KSP unmodded; however should you have any modifications let us know.

I'm running version 1.2.1 64bit version on windows 10

Here's the output log

Full DxDiag file if that helps at all.

 

I am running it unmodded with a 99% clean install. I uninstalled and completely deleted my previous KSP install and reinstalled it using the installer from the site. The only thing I transferred over was a single save file.

I would have guessed it was possibly Community Tech Tree but since you're running unmodded....

 Does this also occur on a new save file?

Saves that are migrated over several versions can have duplicate parts as the tech tree changes, and what you have unlocked is recorded in the sfs, it's unusual to see so many of the same part though.

These additional parts can be edited out, if you upload the save we could take a look.
