The crystal never shows up in the upgrade screen, that's what I meant, I go to a workbench, I open the saber console, create the hilt, choose type, then color, exit out of console screen, go to upgrade at workbench, and nothing shows up at all. I know you won't see the crystal in your inventory, but you get a little blip of having the crystal even if it doesn't show up, all I get after creating a crystal is a item lost notification on screen and nothing.
