How to use -rescan? Or block's reward lost in wallet

[50tugrikov]

My wallet shows "Number of transactions: 11", but in table "Transactions" only 10 lines/transactions. One block was lost.

I tried to restart the wallet with command "-rescan", but nothing happend.

Who knows how to fix this or it's some kind of orphan (but in cgminer this block was not rejected)?

ps I noticed this case in two wallet (Alphacoin (1 block lost) & Nanotoken (3 blocks lost))
