Have you tried resendtx command? No, for rescan, there is only one command 

Yeah, I tried the resendtx command.  It just returns nothing. 
The repairwallet command just returns this:
{
    "mismatched spent coins" : 2,
    "amount affected by repair" : 9.88786700
}
And there is no hempcoind rescan command.  How do you run the rescan?  
Resendtx command never returns anything. It just resends transactions that aren't included in block.
Are you using wallet on Windows or Linux?
If you are using it on Windows, create shortcut, edit that shortcut and at target field add " -rescan"
If you are using it on Windows, you would probably run it with command like "./hempcoind", right? Well, if you want to add some parameter, just append it like this "./hempcoind -rescan"
