If you are missing zerocoins, make sure your wallet is fully synced before trying the following steps:
Open the debug console and enter the following commands:
If that doesn’t get your coins, try:
searchdeterministiczerocoin 0 50000 2
This command may take 30 minutes to complete, it should say done in debug console when finished.
If you are still missing zerocoins, please try to search a longer deterministic range
searchdeterministiczerocoin 50000 50000 2
You may repeat the above to a higher total by increasing the first of the numeric parameters:
searchdeterministiczerocoin 100000 50000 2
searchdeterministiczerocoin 150000 50000 2
If you have a fast, multi-processor computer you may like to change the last number to 4 or more, to add more processing threads in parallel.
