Very strange indeed, maybe it has nothing to do about it, but I just did a "large" buy at bittrex and sent my funds back to my wallet
Everything looks good on bittrex side :
08/28/2014 11:14:37 PM CANN 31267.83728048 Completed
Address: CKrYWyR8kUh1TXnbaF6WMh9rv37Ls53r8C
TxId: 684554baeca5567fe6796de9e67afd3b1dd41d191912c6bb326273ae6004f9c5
but still, nothing in my wallet

I did the transfer before the
bug and it should have been included in the blockchain by now
If you are waiting for your withdraws from Bittrex to show up in your wallet after Bittrex has said every thing is done..Check Site Status on Bittrex to see when the last block was seen for CANN... If its a long block it wont show straight away in your wallet.. just be patiant it will show Bittrex just needs to see new blocks is all..No i dont work for Bittrex but has happened to both a few of my friends and myself..its not a problem you just got to wait for new blocks to hit Bittrex Hope this helps
