I had an item queued with about an hour left as I left town. Later I noticed I had not received notification that it was completed, and it was not in my inventory, vault, or crafting queue.
Do items that don't even exist yet disappear when you get killed, or is there a new crafting glitch?
i think this is a glitch. It shouldnt be subject to the 25% destroyed list if it doesnt even exist. Only your inventory is subject to that. I would bug report it.
