i dont understand, i am mining this coin too, over 2 moths a never had any problem with it.. what pool you were using? and there was a hard fork to be asic resistant but it is some time ago, it was block 138000
ohh....
.....A little over two weeks ago the developer did something with the blockchain.....
What's the difference between a pool?
.... Personally, I have transactions, who had more than 10 confirmations suddenly became unconfirmed.....
