frosty, yes, I saw that screen and I understand the implications, but the saved games previous to that save should have been there still surely - that is the way it works in other games. I wondered if being killed automatically took you back to 'new career', but if that were so, I should not have been able to access the earlier save game even once - but I did.... Perhaps it is as 3Jane says, and there is a 'bug' ( in GWX?). Anyway, I shall do like Jane says and backup etc.
Yes...hydrophone, listen before popping up the snoot. I will do that in future
I think it was probably because I was on compressed time, impatient to get where I wanted to go. Silly ol me...
