"Offline" Ops progress reset/lost

Well there's a weekends playtime gone in a flash, final op against the giant xeno results in a crash, only to discover on reboot all my progress has been lost? Ranks on my weapons, classes, even the other operations show as uncompleted. Great stuff, was fun and enjoyable but that's killed it for me, uninstall and moving on. Shame. Seems I'm not the only one too.
