I been asking Poloniex support since june 28th but they do nothing. After 6 tickets and no help they blow me off. Now they do not even answer my tickets on the subject anymore. I been very patient but 6 months is VERY long time .
It seems like exchanges are set up for 1 output and 1 address and 1 TXid if you have 2 outputs to the same address and the same txid and address you can not claim the second output.
This only has happened to me with this VRC transaction but is IMPOSSIBLE to fix
