The patch worked for my wallet, but my son's wallet lost all the coins that he mined the last two days. His wallet is currently on the right block. Could we have done something wrong that would cause this? Can we fix it? It was only 720 coins, but that's a lot for him.
Thanks so much for your help!
Sent you a PM here so please respond so I can help you diagnose this issue and get everything taken care of quickly

Thank you, DisasterFaster. I cannot reply again to your PM as I have a 2 per day limit. All is resolved now and I greatly appreciate your help!
If you have time, could you answer another question for us? My son's hashrate was 160 when he started mining a couple of days ago, then he followed your instructions and increased it to 260. However, when he installed the patch his hashrate went down to 140 and adding that text again didn't work. Is there a different way to do it that will work with the patch?
Please send me a screenshot that shows the text he added okay.
The patch would have zero impact on mining hash. Maybe he did not leave a space in front of the flag or misspelled it or forgot the leading dash who knows...
