Mass selection glitch? Lost all my gold and fusion items

Today, I used the mass selection feature to turn my VR into legendary to use as myth food. However, I wasn’t able to click the “Sweet!” button to go back to the menu after boosting it. AFter waiting a while, I reload the page, to discover all the items I used to fuse were gone, along with the gold, and the VR was back at epic level 1.
