If you have basic marchers and Grave Locket in your inventory and you use the courier to transfer Shield of the Five+Sac Stone recipe, the Shield of the Five combines with the marchers to form Plated Greaves rather than Sac Stone. I don't know if this is intended or not, but it makes using the courier to purchase in this order a hassle and it seems like the recipe should take precedence over the auto combine nature of Plated Greaves.
This is more of a design-ish issue but I'll put it in the tracker
