I'm trying to use the quote syntax here so if this looks weird that's why. To the above, I just figured that out when I inspected the global_history file using notepad and figured that would be the case. I likely have it set to an extremely high level or infinite (i.e 9999 days).
I opened the auto-save WIN file that I discovered exists for the session I just lost and with notepad thankfully I can read the text since its in UTF-8 encoding. Its very straight-forward so pretty much everything there can be saved but its just non-organizable history to June 29. Its at least something because every time I have a non-prompt recovery its awful having to re-create the session manually and if there is no history, its even worse.
Now with the important global_history DAT file, I opened it in notepad also and can read most of it in plain text which is a huge relief as I can easily figure out what's there and what isn't even in raw sector data when I look using recovery software. I can confirm that only what is shown in Opera 12 is in the file itself without any extra damaged or otherwise history. Don't know what this means recovery wise but I'll find out now.
So no one has encountered this history deleting crash before?
