Problem Detail: I invited my friend to play the Heroes Arena yesterday night. He downloaded the game and completed the training section. However, there had no update or changes in the invitation event so I still can not receive the reward. Moreover,I had invited quite a lot of friends to play the game accumulated number is 8 but the reward for me stopped at 5. Please revise the reward system and provide the reward back to me.
