Well, I'm not sure how it happened, but it appears due to the update, my weakest PC just mined more coins over the weekend than I have mined total over 3 - 4 months.
The wallet has a bird next to the transaction and the the "type" of transaction is "mined." Does this mean it somehow solo mined?
Sounds like you veered off onto your own fork. Be careful moving your coins until you figure it out.
