basically,i've lost 1k coins for a bug. well played dev,well played.
update your wallet to latest version and sync
if you didn't send them, surely they are at their place
It looks like you got a Proof of stake block (which will lock 1000 of your coins for a bunch of blocks) I'm not sure why your wallet doesn't show this. Try updating or looking at your transaction list to see what hasn't been confirmed yet.
