Forum:Armor craft npc glitch?

My armor craft npc in mhp3 is glitched. For "plate" the list of craftable items has stopped updating. Most recent item on the list is narga mail/vest. For all the other categories, it is working fine though. They have upto Rathian and still updating with new monsters.

Any ideas how to fix? Huge bug as it prevents me from crafting full sets.
