Keys no longer save when you leave creative games

Since the 33.10 update removed the “MF_CreativeFortniteGameplay” material function, our keys no longer save when we leave creative games. Ive played a couple of games where keys are used as a saved currency, and can’t buy the more expensive things now because of this bug. Could Epic add the MF_CreativeFortniteGameplay material functionMF_CreativeFortniteGameplay material function back?
