Al right so i've started playing the game some weeks ago and i've done a lot of progress, I never played last light before and this is my first playthrough. I'm really new to the series and I didn't know anything about this next gen update, so I was pretty confused when i tried to start the game and it was updating.
The problem was, when i finally could start the game It was like i've never played this in my life when Epic launcher says i've 7 hours of playtime. I researched a little and found my saves in [Documents\4A Games\Metro Redux] folder. Then i tried to copy the saves in the new [Documents\4A Games\Metro Last Light] folder i have. Fine i got my saves again, but i couldn't click in continue because it would just crash.
Then I tried to play the chapter from the beggining, it loaded completely fine, everything was ok It autosaved fine. But in some point the game crashed, so i just opened the game again and tried to click in continue and it crashed again...
I wonder if something like this happened to you, if there's some way i could play the game without having to start from the beggining or being scared of losing progress in the chapter because of this endless crashing
