1 wood is required to craft an FN FAL gun, just as is the case with many guns. But in the case of the HPFA, another 1 wood is needed for the upgrade. Seems like this is wrong (maybe just human error?) Suggestion is to remove the additional 1 wood requirement from the HPFA upgrade crafting recipe. If we think needing to double the amount of wood for this gun, then double it for all gun upgrades? I hope not.
