yeah that's exactly what showed up when I tried to withdraw Clam before they stop processing withdrawals
at first I got the " transfer from cold storage " message , and it stayed the same for 3-4 days as I remember then they refunded the withdrawal to my balance and stopped accepting withdrawal requests for Clam

IDK man if you still can sell it at good price then that's my advice for you , cause if yobit won't process withdrawals for that coin the price will go down even if the coin is being traded at other exchanges
