I have just started axe crafting myself and was dissapointed to find that the larger axes were vanishing, now the last post here was in May, it's now the middle of October and still not fixed? I thought it was a new bug, or just me, but apparantly not. I am not here to pressure anyone to fix it, it will be fixed when it's fixed, but would it be useful if we had a sticky about this so that newcomers to the game (like myself) don't waste huge amounts of time mining materials and crafting re-inforced double bladed axes only to have them vanish during assembly?
