So I have about 15 hours into the game and I am playing on normal mode, everything was fine until this morning. I played for around an hour constantly using F5 to quicksave, eventually I got killed by some super mutants and instead of spawning me at my last save it sent me back out to the title screen. Tried to load back into the game and it started me back at where I was when I had first started playing today so I went to load but none of my newer saves were there. I got pretty pissed so I stopped playing for a while, came back a few hours later and started re doing some of the things that I had done earlier and lost my saves. Played for a little over half an hour, again constantly quicksaving so I dont lose progress again, ended up getting killed by a behemoth and the same thing happened again, sent me back to the title screen and again I tried to check for my saves but they werent there. Has anybody else had this same problem? Any idea what might be causing it? For me its pretty much pointless to play thinking that any time I die Im gonna end up losing my progress.
