No Ships in VAB load list

[Jaff]

Hi all,

wondering if anyone can help me out with this, I have a fairly heavily modified career going in KSP 1.2.2 saved to a separate desktop folder and run from there. I've had no major issues (apart from a pretty glitchy VAB occasionally) until I loaded it up this evening to find no crafts in my VAB save folder.

the ships are still there in the craft folder and when i try to save a new ship as the same name as one that I know was there previously it asks me if i want to overwrite it but the load folder shows nothing. (this doesn't affect anything in the SPH list)

same problem when trying to open a VAB built craft in the SPH.

 

I've had a quick search and found its likely to be a certain craft that's causing the issue, but knowing which one it is is a bit beyond me

I've enabled debug messages and i get this message ...

"an element with the same key already exists in the dictionary"

 

can anyone help?
