I know this is probably quite difficult and low on the list of priorities, but can I put in a plea for in-mission saves as soon as you are able?
The only real ‘me’ time I have to play this game is before I go to work in the morning - so if I haven’t completed the mission by 7.30, I have to junk it and start again next time. So a mid-mission save-state would be a real boon.
