JClosed: Just an idea, but if you go to your game library on this website, you can download the off-line Deluxe Edition upgrade installers. They are the two files at the bottom of the download page.
It would not surprise me if you can use those installers to upgrade your on-line installed game. If the installer cannot find your game directory, you can point to that one in the installer front end.
When the on-line update drops, it probably overwrite those files, but then you have the upgrade "officially" installed using Galaxy.
That doesn't work, because the system thinks we need to buy the deluxe ediiton so we don't have the installer either offline or online.
Saleerian: Update from GoG would be appreciated. Seems like steam users don't have the same issue.
Yup, I'm speechless on how GOG still haven't solved the issue, they've been saying their system is syncing since yesterday 1 hour after release I mean…
But on the other hand it seems Steam users are facing an issue when saving, some kind of sync with Larian cloud, me and my bf lost 3 hours of gameplay yesterday because of that, my solo run had no issue to save, so seems each company has its sync issues lol
