I installed Thronebreaker yesterday, in the game settings indicated version 1.0.1.12., when the latest version 1.2, and I cant update it, when I click on the update check button nothing happens, whats wrong?
Installed from official GOG.

maybe 1.0.1.12 is really 1.2? I also don't know.

I installed 1.2 from the offline installers a while ago, and the in game settings says 1.0.1.12. I'm pretty confident that it's just that the version printed in the settings was never updated, but it is really 1.2. Therefore it's really likely that GOG Galaxy also does correctly install the latest version (1.2), it just isn't shown in the version number section of the settings screen.
