As you can see. I already have the staff and the sword. I got them though the Niya's (니아) daily offer. I did send a ticket though app support chat. Hopefully they can fix this. But also I noticed this bug the second time. Please add a way to check the player's owned blueprint before the blast to the past happen.

I can highly recommend that approach for future concerns.
