Well, my issue has evolved a bit since my original post. Giving the details in bullets (because I think that way).
I initially installed SIA-UI on our "family" PC. This was the initial wallet address I used for mining.
I began mining on my gaming/mining machine in my basement
I later setup the SIA-UI on the gaming/mining PC and used the "recover seed" process and let the wallet sync. At the same time I stopped running the UI on the original family PC. All of this happened before enough coins had been earned for a payout from mining.
Yesterday in an attempt to check all angles I restarted the UI on the family PC. It was obviously out of sync and took several hours to catch up - I went to bed with it at 94%.
This morning - my payout has appeared on the original family PC after sync completed but the wallet on the PC where I recovered the seed is still showing a zero balance.
I guess now I have a new question - when entering the terminal and using the command wallet addresses I believe I'm seeing the same addresses listed on both machines. Why would the balance only be appearing on one of them?
