I'm seeing this also but have differences from the other reportings of this phenomenon. I use the FTM2012 not FTM2014. I also mostly sync from Ancestry to FTM (rarely using FTM to edit my tree and then only to clean up things like location names). Also my last sync was 4 days ago and I have made no changes in Ancestry yet I got the "missing Home Person" message when I logged in this morning. However when I accessed my wife's tree I found she was properly set as her Home Person. It's also not specific to one computer. If I access both trees on another computer I experience the same results as on this one.
