One thing : how the heck do you lose your endgame auto-save? Those things have their own spot in the list of saves, they're named differently, you would have to willingly delete them to lose them!
Yeah that would make sense, but when you have a HDD failure and reinstall only having your steam saves to go off then you're screwed.
Once again my temper got the best of me, I'm stuck in extenuating circumstances and didn't realise the position I was in. Ah well, enjoy the DLC.
