I was soloed  10 days,but i found 2 problems in last 48 hours .
1. In 10/10,I soloed a massive csd that I was check the mining tools diff from 6.1 to 3.8. I guess the wallet was forked,but i wasn't change anything.
2. I deleted blockchain and rebuild the wallet. the wallet could't connected peers well. the wallet forked again?
