I installed the most recent update of GoG Galaxy the past week or so, but I didn't notice until this morning that since that update all the manually added games I had linked to GoG Galaxy were gone. I didn't notice right away because I was busy with one game and when I went to check my installed library this morning to start a new game, it was then when I realized they were all missing.

The games still showed up as "owned", but they were no longer linked for the .exe, thus, no longer showing up under Installed games. I had to go through and manually link them back in again.

This may not be an issue for a lot of people, but I've been slowly working on backing up all my physical games and creating functioning .iso files. I'd hate to get my 100+ collection of physical games linked to Galaxy and every time it updates it drops the linked files.

I Just wanted to point this out so hopefully it won't be a continuing problem in future updates.
