Is the instant payment working? Haven't mined for a while and decided to get my accumulated coins. First time it said "wait for auto payment" then it said "please wait 2 minutes". Apparently the second is a flood filter, but it means the first request is acknowledged. Though it isn't, since 2 hours later my balance is the same. Same thing happens now.
At this moment the payment system awaits for new batch of bitcoins from cold storage. Sorry for the delay, payments will be resumed very soon. Sometimes this happens when people withdraw more funds than usual (this time, possibly, caused by BTC/USD rate jump).
