[Bug] "Cannot create a file when that file already exists." Error when editing JSON

[kekivelez]

Description

After enabling JSON editing, when changing a data value for mission progress NomNom crashes with a System.IO.IOException and a message "Cannot create a file when that file already exists.".

Reproduce

Steps to reproduce the behavior:
1.Edit JSON for save
2. Search for timed mission (Bio_Ship2 is the mission I am encountering the issue with)
3. Set the "Data" key to 1
4. Click ok
5. Accept the prompt to save changes
6. Go to File > Save account
7. Profit?

Expected Behavior

json file changes saved without NomNom crashing. Additional clarity on whether the confirmation prompt (the one that pops up after editing the json and hitting ok) saves the changes to the save would be a nice bonus (is it supposed to save the account for me or is the user supposed to manually hit save account despite that confirmation?)
