Just noticed something a bit suspect on Zpool. My unsold (immature + confirmed) coins completely disappeared about 2.5 - 3 hours ago without appearing in my unpaid balance or reappearing in my unsold coins. Usually unsold coins gradually get sold and credited - it doesn't tend to have sharp changes. I've never seen the number essentially completely deplete before! It is gradually going back up now as I'm still mining but my graph is showing a big drop. I'm a bit miffed as to where and why my unconfirmed earnings just disappeared.
