I upgraded my liberate weapons with redux potentials. After playing on Phantom for a while i swapped them over to my main class hero. I just noticed that the weapons have removed the redux upgrade. I've essentially lost 720 Luminfragment Emels due to this. There's doesn't seem to be any note regarding that the weapon change will do this. I was under the assumption that changing a weapons potential to its stronger version would carry over during a weapon category change but that doesn't seem to be the case.
