As I said, I have 45 people invited to that tree. I'll loose all of them if I upload a new tree. We communicate a lot. I know I could re-invite. It's a hassle that's totally unnecessary. I'd prefer to fix my tree.
Oh, and by the way, it's not as easy as you say to upload my clean tree to Ancestry. I've tried numerous times to upload and the stars haven't aligned yet. I have to get a time when my network and your network and servers are all cooperating and I happen to get a connection to stays connected. As I said, I have over 45k people, 800k records and 30k media files. It's take quite a while.
