confirmed this morning by Poloniex that suprnova is broken.
quoted from Poloniex staff ...
"It seem that transaction was sent without a xmr payment id"
Till this is fixed can't mine at suprnova.
Sad considering this looked to be decently maintained but appears pool operator ocminer is too busy with pascal these days.
I'm mining on my own pool and I also withdraw to polo.
even if you send a payment without payment id to polo, just send them the TXID and the exact amount of your payment and they can still credit the amount to your account - since it's been transferred to their account...
There are three checks in the pool software that sending to polo's address is impossible without payment id, first when entering the address, the second when verifying the address and the last when sending to that address.. I doubt it was really sent without polo payment id.. IMHO those ring-ct's have problems sometimes since XMR updated / forked.
