I wanted to mine some Litecoin in the last couple of days and for the first two days everything was all right. But after that, I restarted my miners and I got way less than before. I also repeatedly get the message that zpool has run out of LTC currency but the message goes away again after some time. However the last block that zpool found, was 4 days ago. Can it be that zpool completely ran out of LTC and the message goes away by mistake? Here's my address in case it helps: LTzVdcWKmg2pEUTuwTXN1mSPhWMtDUCABM
