I have a hidden level setup, it's sharing the same UI as the endless mode. If I collect 50 coins in the endless, and die I can share that amount using the share button. When i enter the hidden level and collect 150 coins, then return back to the endless, the coins will show 200, when the character dies the total shows accurately the amount collected in both endless and hidden, even if coins are collected after returning. The problem is that when I click the Share button, only the last set of coins collected after returning to the endless mode comes up in the shared message.
Also, Current Coins only reset to 0 in simulator. On my device it doesn't reset to 0 for each restart.
Update: The coins resets to 0, unless entering that hidden level. Once player enters the hidden level and returns to the main, coin score never resets to 0 upon death. Only solution is to quit game and restart.
