I've been playing a bit more of adventure mode recently, mostly because I find the procedurally generated civ sites pretty interesting. One thing I can't really seem to place though is the distribution of furniture.
Human hamlets are pretty consistently bare. I've only once seen a house that actually had a bed, and the rest were just empty log cabins. Human towns tend to be a bit better - on a few occasions I've found homes that had a "complete" set (bed, cabinet, chest and a table/chair set) but for the most part they seem pretty bare as well. They do tend to have more chests/cabinets, but most homes are still littered to the brink with random articles of clothing. Shops suffer from the same issue, but I did once find a shop with a table. All the sellable items were stacked on this single table. Are shops intended to have more tables to "store" their items? Because I don't think littering the floor with merchandise is intended to be as common as it is.
Dwarven sites seem to handle the whole furniture issue a bit better. Almost all the homes in the hillocks and mountain homes had a complete or near complete furniture set. I've never seen any furniture items in elven sites, so I'm not sure if they simply don't procure any of those items currently, or if there's something broken in their entity behavior. Goblin sites are so laggy, I've been unable to actually visit them for any prolonged amount of time to see how their homes are handled.
So, those anyone know how the game determines how individual homes get furniture? Human sites seem to lack basic necessities most of the time, in stark comparison to dwarves, so if I can find definitive proof that something's not working as intended, I'll probably write a report to the bug tracker.
