I think there is a problem with your wallet because I was mining on https://pool.sumokoin.com/ and I mined 281 sumokoin and you can check my address is "Sumoo4HS4diMPerPWKETgiFjxMXjsWr2eJSUgCE99kkTJPrMUnx7Lk1WJVY2fCTWfdhyxpFdas3vmMx q8Tr6SdTmEYpSkpc5kkb"
and when I installed the graphic wallet and restored what I has using the list of words I got only 185 sumokoins
It says that the last block is 21300 is that's not correct how can fix the problem?
