Their is something wrong here.
Developer(s) - i had over 200 immature and the confirmations were coming through. Balance showed 30 HUC. Wallet was stuck for a while so closed the wallet and start it again.
Now all at 0 but still shows 204 transactions and nothing in transaction log.
This is highly unusual.
Same happened to me, except all of mine were confirmed 350+ coins and I lost them all.
I just had that "warning" issue too, still have my coins after deleting everything except the wallet.dat and starting the sync over.
