Mighty League Locking Up
The Mighty League keeps locking up, but after I've used valuable power-ups and flinging the bird. The only option is to close the app. Upon reopening, the used power-up is gone, but without having received any benefit from it. Rovio keeps screwing up these games and is at risk of losing long-time players, in their never-ending quest to tweak the game to prompt in-app purchases.
