I did not make the merged mod, I'm only 'advisor' with it because Smarmbot used parts of XC_Bags.
As he said in the Steam discussion already, he did not include all of XC_Bags' recipes, he left some out, among them the recipe for fire arrowheads from what I understood.
If you'd know how to unpack the mod, you could re-add the recipe for yourself, but I cannot change XC Encounters because it's not my mod, it's Smarmbot's ;-)
I have never taken a close look on Epic Encounters internally, so I don't know, if the guys also added their own recipes. If they did, you cannot take the recipe files from un unpacked XC_Bags and replace the XC Encounters files. In this case, a merge would be required.
Maybe Smarmbot is willing to provide yet another 'Steam supplement' on Nexus only for crafting with all the original recipes from XC_Bags, but that's his decision.
In pure XC_Bags, it's the oven in the crafting area, the cooking pot, that is usable for the recipe.
