http://imgur.com/a/RAzvmHere is a before and after. You can see my immature balance in pic #1 and you can see that my wallet had not synced fully.
Pic#2 shows no balance but still shows transactions. Now, if I close out my wallet, and re-open it, i have no transactions in my history and 0 balance. This is the third time, the times previously I lost 150k, and 90k CAC.
HELP ME.
Were you solo mining when the wallet wasn't synced? If you were I bet you were mining on the wrong fork. When you synced the current blockchain didn't see what you mined, and poof they are gone because they were invalid.
