Dear EA_Gunner, your answer is very generic. Can you please elaborate on what has been checked? For example can you confirm if the rewards are assigned to my account? I always do multisim of all challenges (press one button), so I don't really understand what would I try to fix on my side. Please elaborate.
As to my understanding this is either freeze in the UI and the logic of the game work fine, i.e. rewards are added to the account (this doesn't worry me) or it is a bug in the game and the rewards are not added to the account even though the possibility to do the challenges gets blocked. In the second case the bug is probably due to lack of a proper transaction isolation. That is, the transaction should always complete as a whole (rewards are granted and challenges are blocker) or fail as a whole (nothing happens). Can you confirm that the transation does not happed partially (challenges are blocked and not all rewards are granted)? It should be an easy check as I always do multisim of all challenges, so I should always get all the rewards.
