I have some confirmation that the GoG Galaxy client is causing the disappearing saves problem. I just played Saga of Aielund all today with my GoG Galaxy client shut down, and I exited and re-entered the game quite a few times to check various things online. None of my save folders got corrupted with spontaneously appearing extra .sav files.
Then, towards the end of my gaming time today, I started a character in NWN2, which requires that the GoG Galaxy client start itself before the game will boot, in my current install.
Lo and behold, after I exited NWN2 with the GoG Galaxy client running, almost all of my save folders for NWN1 had been corrupted with extra .sav files from both my Saga of Aielund mod, and bafflingly, from my last runs of the OC.
Could someone instruct me on how to uninstall the GoG Galaxy client from my computer and still have access to all my GoG game installs, without losing any save files?
My current game install main folder for all games says "GoG Galaxy", so I am not sure what will happen to all my GoG game saves if I uninstall the client, as I now want to.
