That's the exact problem I'm having.

I've been around since 2013 but my old account was locked after the 2015 hack and I don't care enough to try to get it back.

So my 3 XMR plus your 2, and another 0.6 that I've learned of from a different member now totals $900+ that has conveniently disappeared.

Anyone else mining on xmr.suprnova.cc for any period of time, check your payouts, bet you will find some missing XMR also.
