It's just the charts, if your miner is mining, the shares are being mined and your payment will not be affected.
This current stats freeze is a bit different though. During the previous stat freezes, the JSON api's that BFPCoin and others use were still updating. This time they are not. So it seems to be a bit more than a "front-end" issue. It's lamentable that we can't seem to get more than 2-3 days uptime on the stats. Label me a noob and a hater if you wish, but it's not like that at all. I really like middlecoin, just want to make it better. Wish he would take me up on my offer of database help. It's what I do for a living.
