Yeah gog-staff WHAT DID JUST UPDATE???? Have I to guess now which games are meant? Again: 3 Updates in the library and then in the library there is no game updated... And I'd thought the gog-site could not get worse than it was already. Disappointed. Pretty disappointed. Again.

No Results Found has been updated to the latest version.

It's not the latest version. It's the one before that. There's already a newer version on Steam.

Be careful though, the newer version on Steam replaced the original soundtrack with a Gregorian chants version. Also, all the moose where replaced by llamas.

Lovely! +1.
