How many furniture 'packs' did you buy the first time?
Are you certain it's the same guy? Did you finish any quests in the meantime?
Yep, it's the same guy. The Jarl Advisor. I've only bought the room pack.
I've finished side quests and progressed through the main quest aswell. Unfortunately I don't have any saves from before this happened.
This is really sad, my house looks like an abandoned warehouse.
