I was completing the mission to unlock her, then suddenly the app popped an error screen and the game rebooted. After that the unlock mission gone. Wtf is this? Anyone experiencing this?
Back up your data and delete the app. Re-download and load up the back up data. Any time there's a weird bug, I do that to fix it. It happened to me during the Yubel event. 🔥's cards were all glitched. She was summoning the level 6 Revival Rose with no tributes. Her card descriptions were blank. She played Veil of Darkness in face-down defense mode at one point. The re-download fixed that.
