Bug - Normal Bug in Daily Reward

[PapirriPaps]

Just a moment ago, I opened the daily reward calendar but didn't open, then I closed it and it gave me the reward (10k coins) then it opens again and gave me another 10k, and again and again

It's a known bug. The extra rewards aren't saved on the server though so after you restart the game it should all go back to normal.
