Has anyone else had items disappear from their crafting queue, taking the mats with them? It has happened to me three times that I know of, purple top-level items every time. The first two times it was Armek ship armor in cybertech, but most recently it was a lvl 47 color crystal in artifice on another character. All three times the items were part of several items in a queue, I logged out and when I logged back in later the queue was complete but not all of the items were in my inventory -- the mats, though, were gone.
The first time it happened I thought maybe I was just confused, but from then on I was watching like a hawk and there is no question about the next two times. Sometimes stuff just disappears. Is this a known issue, or caused by certain known conditions?
