The gunsmith at the farm (Arcyte 99-40) seems to be bugged so that when i turned in enough gun materials to get an engram, the bar was completely full, the text for a faction engram appeared, but there was no engram for me to click on, only an empty space where the engram should be. I have tried closing and reopening the game, reloading the blizzard client, and resetting my computer, nothing I've tried so far has worked.
