I successfully set up a masternode and got reward a couple of times in amount of 21.xxx coins.s
I had to restart computer and when I started masernode again it was not starting and found the mined amount turned to 7.xxx coins.
I sent 25k from mn wallet to same mn wallet then I could start it again.
I updated with newer version of wallet and but some reason I had to down load the blocks again since the moving the blocks from old wallet didn't stop resync'ing.
I could restart the mn without problem.
Then I had to restart the computer a couple of days later and I encountered the same problem.
Also I can see my mn from the list after starting it but I can't see it on the list after few hours.
Then I start it again and see it on the list.
Also the wallet is going unresponsive every 10 to 15 seconds?
I've had similar experiences with the wallet and masternode.
