yeah... i just lost my blocks as well ... wtf is going on
thats normal for a new coin with such a low difficulty. lots of orphans. just keep calm and keep mining. make sure you have the right version of the wallet.
When you're mining on an outdated version of the chain and you find blocks, they will appear as immature, and then boom, chain updates and everything becomes orphaned. Happened like twice to me in less than 5 minutes now
NOW!

{
"blocks" : 53194,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"difficulty" : 0.00093260,
"errors" : "",
"generate" : true,
"genproclimit" : -1,
"hashespersec" : 1724,
"networkhashps" : 744062,
"pooledtx" : 0,
"testnet" : false
}
That's can't be right. 744Kh/s network hash rate? Nahh... I have 2mh/s nethash and I'm at block 55k now. See this:
