Re: Crafting npc
Seems to be in working order for me.
Can you make sure you are putting all the ingredients into the Crafter NPC. You do this by clicking the item and placing them into the designated slots on the NPC, alternatively you can right click the items in your bag and it should automatically place them in. Once they're in you should be able to click the 'begin build' button at the bottom of the page.
Also be sure the ores are equal or greater purity than what the NPC states.(it shouldn't let you put them in if they aren't of high enough quality)
Hope this helps.
