Hee, Maybe may this valuable for the guide: While i'm fletching Yew logs into Yew Longbow (u), WITH FULL INVENTORY, one of the Yew Longbow (u) disappeared and replaced by the strange rock for Flechting skill. > I also received a message: "Something Odd happens to the Yew Longbow(U) and you are left with a strange rock" < I think it will also apply on skills like Herblore & Crafting. It may be useful to add a warning on the guide that this occur. ;) Happen also by Cooking with full inventory. The Burned fish turns into a strange cooking rock.
