Recently, Larian Studios forums has introduced a new version of 1.4.2 patch to update Divinity II: The Dragon Knight Saga and a hotfix for Divinity II: Flames Of Vengeance, fixing some bugs in the RPG expansions. A few words have been also discussed on the digital distribution versions on their site "Some digital distribution versions (such as Steam) have their own system for releasing patches, hotfixes etc… If you bought your game through one of these vendors, then you will not be able to install this hotfix. We are working on getting it distributed through those services."
You can download the hotfix for this game from below links:
