Hey there! We launched the game with build version 424 on GOG GALAXY and 436 for Offline Installers. While there’s no noticeable difference in-game, GSC Game World decided shortly before launch that build 424 would be the "final" version. We were able to quickly update GOG GALAXY to 424, but to ensure everyone could start downloading the game at launch, we used build 436 for Offline Installers, as there wasn’t enough time to regenerate them with build 424.

Yesterday we rolled back the Offline Installers to build 424. We apologize for any inconvenience this may have caused, but this approach allowed us to minimize delays for players.

As mentioned, the differences between the builds are minimal and likely unnoticeable in-game. Nonetheless, there will be a patch that will bring all versions to the same build. Thank you for your understanding!

Hey everyone! Our apologies for this, as we know it can be very inconvenient to some of you, but as you've noticed when you have the 436 version of the Offline Installers, it's not possible to use the latest patch.

In this case, you'll need to redownload the game with version 424, or as MarkMoelders suggested, you could try using GOG GALAXY to repair and update the game.

We're very sorry about this and we'll try to avoid similar situations going forward. :(
