Lost save game after streaming from 2nd computer

Hey!

It seems I have just lost all my saved games after sharing the screen from a second computer via steam. Might there be a way to recover them?

What happened: I’m playing for a long time on computer 1 (a mac) with some 10 saved games. Then I installed airport CEO on computer 2 (windows) and played a new game there. My partner took over that game and I saw the option to stream it on computer 1 (assuming it’s passive observing).

When I wanted to load one of the older games on computer 1 only the saved game from computer 2 was available. There are no obvious traces of the older saved games in the application support folder.
