I've been trying to collect some of the Pattern books (used for tailors) for a while now, as has a friend of mine. I've never seen them restock, but there are several in the user stalls, typically by just a handful of people, for very high prices. I thought that this may have just been beta users who stocked up before the stock changes, but my friend mentioned that he's suspicious a bot has been used, if the books are even restocking in the stores at all.

Has anyone seen the books actually restock, ever?
Or, does anyone know of a bot? I'm not about to throw a fit or get anyone in trouble for the bot, I'd just like to know so I can stop wasting my time refreshing at the 15-minute restock times.

Any info?
