Can't claim my Fire Demon's Tome

    • Can't claim my Fire Demon's Tome

      Hello everyone ^^,
      (sorry for my bad english, I'm French)
      I create this thread because I cant claim my event rewards, the button is grey (screenshot)
      Yesterday, I noticed the same thing, and after some reconnections and relaunching the game, nothing... And I do not have any quests about it...
      Can you give me some help, or answers, whatever you are, player or dev :3 please ?

      (ps: sorry for the french language in the scrennshot, just to show you my problem ^^)
