I have found 9 out of the ten decoration disks, yet i am having trouble finding the last one. I looked at a guide and where the last one was placed, but sadly did not find anything at all. It said the table right of Magnus's dogs bed, all I found was papers and a mug, but no disk. It might be stuck, I don't know, but I do not want to start it over after how far I've gotten. Any help?
