I noticed that the old barn pub has a "interesting" list of possible consumables (too many IMHO, what's the difference between beef steak and bison steak really), but one of the combinations uses "steak". I built a butcher and it can only create "beefsteak" and I can't see any way to produce the correct item. Is this a bug?

TBH I think there are too many different items produced - if the butcher made a few types of processed meat from the raw material it'd be a lot easier to manage the end-product, having 1 speciifc processed type from each animal seems excessive.
