Had a crash at about 19:00 and rebooted. Sequence bin reverted to last save at 12:40. No problem I thought - I'll just dig it out of the Attic. This is my Attic. Massive gap in save times between 12:56 and 19:01.
I just lost 6 hours work. Absolutely gutted. Anyone any ideas why it 'pretends' to save but isnt? It was saving some bins and some Attic bins - but not my crucial main sequence bin :(
