I have only now read this thread what happened to me was i found i had duplicated part of my tree ( before i found about the new merging), so deleted several people and then tried to reconnect the lost people to the new part of my tree. I could see that what i did was right that is the right people in the right place but then i noticed in another part of my tree completely screwed up with dozens of connecting links all over, lucky i had saved my tree two weeks earlier so by deleting and saving back my tree and spending the last 2 weeks ignoring over 9,000 hints i'm to square one!!!!
