Somebody staking?

It works in wrong way. I mined some coins because my hardware is really bad, but just now I see less coins mined with some coins staked. Yesterday I had over 100.000 coins mined, now I have 95.000 and with stake about the same. Stake removes some coins from your mined balance and full balance remains.

Also, stake announces three hours or two days or one minute to reach some coins but this time moves at its own caprice but in a slow way, announced coins (are announced coins numbers in stake icon?) change in a going down counter.
