What you were expecting to happen, and what actually happened?
Completed Priest class quest during XP event, but did not change to it, and powered down my phone at the reward screen. Did not look at priest again as the event was over. Subsequently completed all quests in Whitehelm. But now when I go to the class select screen, Priest is locked. When I click on quests for Whitehelm, it says that there are none for me.
What are the steps to make it happen again?
I logged out at the class reward screen.
