Crashed on save of character & cannot re-open - save parse "startIndex" out of range

[lewisandrew]

I didn't make any changes to my character (1.sav) and clicked Save. The app then crashed, and I cannot re-open the character save and get dialog error pop:

Error parsing save: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: startIndex

Here's a zip of my two files

I started up BL3 and my character got wiped :(. Any way this could be restored?

I fortunately had a backup save that was only 2 levels behind, so I just had to replay to gain that progress back. From the looks of it, the file that I'm seeing written to disk when I do a Save or a Save As is 2KB, where the original file I am editing is 658KB. I had the debugger open when I clicked save but the entire apps crashes/closes immediately, so I can't capture any info on it. Any other way I can debug or retrieve logs of the Save attempt to help diagnose the issue?

I can't really debug it without having the correct (uncorrupted) save so I've got to have that. If it's erroring during saving, of course the file is going to end up corrupted; When I save a file, I reload it in the GUI to try and point out issues like that more easily.

Also as a note, the editor comes with a backup option, I suggest you use that anytime you're doing editing on a save you really treasure.

Here is my uncorrupted file.
