Stumbled upon this while trying to fix some configuration issues. For the next poor sop who stumbles upon this thread, tries the fix, and has the save disappear:
type = Crew
not
type = Scientist/Pilot/Scientist
This only fixes the save file disappearing if you edit it - not orange suits going tourist problem. Still working on that one
Edit: Figured out orange suits going tourist again once you reload the save. Copy and paste "lastupdate" time over "lastonkerbin" and "lastmeal" times (found by the per-kerbal isgrouchy field). They'll go tourist again in 15 days as usual if my suspicions are correct, but you can at least undo the damage done by unexpected touristification of orange suits in a pinch
