I find myself making duplicate recipe orders so that when I have more than one of a particular craftsmen type, they can team up on the job instead of doing different things. Some things I like having only one person doing (like carpets/tapestries/plushies, since I want them to be making a variety of them rather than doing all one thing), but other things I really want everyone to be working on (like boxes, because if I don’t have them it’s usually because I need more as soon as possible).
It’d be really cool if I could set the maximum number of crafters I want on a give thing. Though I guess since most things are either just one person or everyone, it might be easier on players to just have a “bulk” tag that just made it have no upper limit to how many crafters can be working on it.
