Yes the arena from Extravangaza until now have a bug like this, actually you open game and close/exit, and open again, without play, the task have only 2 , and get 75 token. Its bugs of 75.
Oh! So it's a recurring bug, I see. The missions are auto-completing and auto-claiming the rewards even without playing. That happened to me too, I thought it's just a visual bug and didn't mind it at all. Thanks for answering! I hope the devs fix it.
And there are another bugs, in same Tab, daily activities Lawn of doom.. Can not close X, only by force quit closing.. and here solution if you got it...
