Sources that are removed
I recently had multiple sources removed from someone in my tree. There was no reason given and the person will not respond to messages. In the 'Details' history, I found some of the things that had originally been put in and managed to replace these. There were other 'Sources' that were detached or deleted that I can't access. Under 'Sources' there is no history of sources being added or changed. Family Search needs to make a history for sources like there is for details. Added sources do not always show up in details, so if a source is removed it is lost forever.
