Dear NiceHash please check, I have problem with Etherium today mining profitability and last payment
https://www.nicehash.com/?p=miners&a=999&addr=15uM7g5Mnd7ZTuYhbDkFhHCdJrdekD3EZu&l=0
Unpaid balance decreased, but ni incoming payments.

Something wrong with Etherium mining.

Why Unpaid balance unexchanged decreased to zero 3 times without real payment or adding to Unpaid balance ?

I have problem with last payment, please check ( Unpaid balance decreased, but no incoming payment to wallet ) .
