I have also started a ticket at Yobit to ask what the hold-up is with withdrawals there. It looks like it's been locked for more than a month and there are no flags on the exchange until an attempt to withdraw is made. Very bad practice on the part of Yobit if you ask me.
Yes, I can only apologise about YoBit but there's nothing I can do.
I have updated our github code to the latest release as they requested but it hasn't made any difference. I've contacted them and I'll contact them again. I am receiving the same treatment as everyone else. I have no special dispensation sadly.
