When we pushed an update over the weekend we also pushed a bug impacting some new users. For now we have pulled the Daily Reward, once we get the bug fixed we will re-enable the daily reward. Accounts that took advantage of the bug and did not report it will be dealt with on a case by case basis. We apologize for any inconvenience. This bug does not impact your current day streak or time to collect, once the fix is pushed you will be able to collect as usual and will not lose a day.
Daily Reward collection has been re-enabled. As stated above you will not miss out on any rewards you have pending for you, we just needed to take down the collection process until this was fixed. Thanks for your understanding.
As far as I know it repeatedly rewarded some players with either energy or stamina. Day one boosts over and over. A pity it didn't happen to me.
