Hi @DeadpanSnail apologies for the late response.
I am also sorry to hear that you are experiencing an issue with the quest 'War in the North'.
From what I remember I can't recall needing to play a game of Orlog in this particular quest. I have also checked a walkthrough and cannot see this quest objective.
Can you provide a detailed description of what happened as you mentioned you were instructed to play a game of Orlog, then after logging into the game you were presented with a still frame of Orlog. Did the game crash previously, or did you close and exit the game during the quest? If so had you started a game of Orlog?
Could you please provide a video that demonstrates this issue.
I would recommend uploading your video to a video sharing platform such as YouTube, you can then copy the URL link into this thread.
