Android 4.1.1
I believe it occurred during one the times the Lava games kept freezing these last few days.
My 'Parfait and Potions' challenge disappeared when there is still over two weeks left. 'Patching Things Up' still exists and is waiting on P&P. I only have Pumpkin Parfait available and was working through that.
(I both waited a few days and rebooted but it did not fix.)
I'd love to get the challenge back.
