Thanks, that is simpler indeed.
I reversed the changes in the Config folder and tried that, but get the same result.
The Mission entry in the scenario presently:
Code:
Mission:Soyuz\Mission
MISSION Soyuz-18-1
MISSION_FILE Customizations\Soyuz\Missions\SoyuzMissions7KT.cfg
CLEANUP
END
The Mission name is also present on the default missions file, so stays the same in this case.
I've checked the spelling and also tried it on a more recent cleaner install I have where I didn't change any of the Config stuff for Missions, same crash.
Edit: not sure it matters, this is O2016.
Thanks again for the quick reply.
