As I understand, the crashes of the GalaxyService happened, when Galaxy tried to send achievements to the GOG servers.
Now I am not much of an achievement hunter, but for some games I like to have them and some are missing from my profile.

Now that the service is supposed to be repaired, it would be cool to get those to the profile page as well. I tried to play the according game again, hoping that Galaxy would synchronize the achievements with the server when I quit it (like the cloud savegames), but no suck luck.

Is there anything that can be done to force synchronization of local data and server data?
