Its known - Restarting session breaks completed items (they'll need to be reassembled) - And You'll need to ensure that only the matching item is offered - If you have a steel greatsword and an iron greatsword both in the customer area, and they want iron, but see the Steel first -they will get stuck - trying to buy the steel but being denied because its not iron. - Its best to just have the parts made/bought - but not assembled, and then assemble them when a customer asks.
