No matter at which point I quit in the game (I ran thru 2 campsites at most), when I re-start the game, the "Resume" menu item is always unselectable. I always have to choose "Start Game" to play. Also, when saving, it doesn't show any other saves.

I can see that ~/Documents/"My Games"/"Tomb Raider" always updates lastcamp.dat, profile.dat, and save1.dat files whenever I pass a checkpoint or a campsite, so I am sure it is saving the progress.

It just doesn't seem to detect the progress when the game starts.

I'm using Linux with wine 9.8, but I've seen issues with gamesaves in other Tomb Raider games running in Microsoft Windows, so I don't think it's related to wine.

Any idea how to resolve this?
