Hi, after a long time away from the game, I bought the latest DLC and wanted to play. At first I couldn't install it on Galaxy, so I just downloaded the installers and started playing. It works, but not every hour or so Galaxy will tell me DD has been updated. And also every time after closing the game. What is going on?

Latest DLC has still quite amount of bugs and patches are released very often.
I'd try to download current version of offline installers to see what happens.

Thanks for your answer, but, like I said, it updates every hour or so. I've got the update notification over 20 times now. And the DLC's were installed via offline installers already. I'll try to uninstall everything

Yes, I understand, but what offline installer version you used?

An older version from yesterday or the day before.

Uninstalling seemed to resolve the issue. Apparently the Galaxy app can't handle offline installers very well when it comes to updating.
