Bug/Exploit?

[Tom H]

When crafting cords, if you start with a .03 weight Fine bird leather and add several pounds of lesser quality material of any acceptable type it seems that the Fine starting piece can define the quality often. Maybe I just got lucky but I've seen this several times, wherein I get 5 Fine cords from primarily lesser quality material.

It's a general quirk with crafting. If something needs a single kind of item, trace amounts of a better quality causes the whole lot to be "rounded up" one step. This differs from the case when multiple types of items are used.
