Hi,
I have an issue too with a wallet.
The minting work, i've received 5.28 fac for 1k fac
but my wallet didn't syncronized today, i have delete everything except wallet.dat and peers.dat
My wallet is now synchronized but other minted which corresponded to 10k are generated but not accepted and 10k fac are no longer in the wallet and no in stake
Each new minted with 1k has disapeared.
What can i do ?
type repairwallet in console and hit enter..Once wallet repaired, close wallet and start again.
it returned this:

{
"mismatched spent coins" : 4,
"amount affected by repair" : 4000.00000000
}
Sweet got my coins to show again, but no stake shares are being confirmed.
