problem is that with hats, you put them on your head and they remain in your inventory... furniture you place as an object and it is removed from your inventory. Each item you get would have to have a timer on it... that means if you bought like 500 items in one go, then you would have 500 timers running... it isn't too hard for one character/account, but imagine having like 2000 people who decided to buy 100 things each? 200,000 unique timers suddenly starting up might cause some issues :3
