Noo I solo mined all night and was getting blocks this morning I sent some to cryptorush did not show up so i closed wallet and reopened and all the blocks I solo mined disappeared ... 7 million
did your check your transaction history page? is it empty or does it show your mined transactions?
or did you setup a second wallet for solo mining?(i use one - so asked)
or did you setup a shortcut key for the qt wallet and used a different datadir? if yes you could have started the qt from the start menu or through the main qt icon, which would have started the the blockchain from the roaming folder. try searching for the folder "noodlyappendagecoin", if more than 2 folders(1 wallet folder and 1 blockchain folder) show up then what i said would have been the case. it could have happened even if you had selected to automatically start the the qt wallet in the option menu.
i've more than 30 different wallets in main computer and for some coins have 2 wallets and have seen this situation many times.
