RE: Official Bug Reports Thread
I completed yesterday's challenge, but instead of accepting the rubies I just started the new challenge. Normally there's a pop-up and I get the rubies, but very rarely the rubies are not awarded. Upon returning to the challenge menu, the "claim prize" button is now grayed out. I think this has happened about once a year or less. Last time I thought maybe I was just seeing things but today I was paying attention.
