Divinity Dragon Commander Imperial Edition is 90% off on the GOG side, why was this not also applied to the Steam version of exactly the same product? I would like to buy it on the Steam side as well even if the discount was not quite as high, that and I can't just buy the base version and upgrade it because the upgrade option is not on there as an option unlike the GOG side.

Really wish Larian would fix this, why you would be lazy like this during the winter sales makes little sense when you have fans of your series who just want to add a missing Divinity title to their library...
