Hiya
i tried to withdraw crave from bittrex and the transaction went through and i verified it in my email. the withdrawal shows as completed with a transaction id but it does not exist in the blockchain. This was fifteen hours ago...
What to do? Mailed them but they have not answered yet...

I have faced same problem with other coin months back but i got my coins in my wallet after 24 hours. So i suggest you to wait for 24 hours and if you don't receive your coins then submit the support ticket again. Also you can tweet your problem on twitter
