Any news on this yet? I'm also in a position where the game tells me to buy the DLC but I couldn't even if I wanted because the store thinks I own it.

So far nothing, they asked me to send them a screenshot of my bonus section to prove it's not there, which I did and also sent them a link to this thread to show that I'm not the only one with that problem. Did that on the 9th and so far they didn't reach back at me :/ Hopefully they got it as a bug report.

Hey everyone, yesterday they sent me an email saying they transferred my ticket to the technical support, and now the DLC actually shows up in the bonus section of the game on the galaxy app. Was the bug fixed for you too?

Just got around to checking again, and no, nothing's changed. I own the DLC according to the GOG store, but don't have it unlocked ingame. Contacted GOG support about it just now, will report back once I got a response.

Alright, GOG support was able to help me out. Refreshing my account did nothing, but they linked me the separate installer for the DLC, which solved the problem. The GOG galaxy client thought I had it installed but apparently that just wasn't true.

The new clan of Lion is released, but the clan of Eagle is still not added to my viking-age edition. What a sad story.
