How old is the save? Only old saves and really new saves will work. Is it all saves?
I'm no longer sure my description is correct. Looks like there was something messed up with my savegame directory: Auto saves and quick saves worked normally, but regular saves would not show up in the Load dialog. Instead, for each time I saved normally, an older savegame from an earlier playthrough (which had all vanished at some point in the beta phase) reappeared. So, chances are quite high that I simply mistook a broken save from two weeks ago for the new one that I expected but wasn't showing up.
I cleaned out my savegame folder and everything seems to be working normally now. I'll close this for now and let you know when either problem reappears.
Nothing extracted yet.
On my machine Half-Life still creates broken save files. When loading one of these saves I see the map from outside, have no weapons and can't move. So, the description sounds pretty much like issue #1387, but that's supposed to be fixed by now.
