I was just trying to copy a person from one file into another through Files>Compare Files. I copied a husband and wife from File A to File B. Then, I went into File B to connect them to their son and each other, and had these problems:
1. Sources - sources were not copied over, and Memorize does not work between files. I really need the Sources to be copied over.
2. The Marriage tag wasn't copied over. I attached the parents to the child in File B, selecting the existing father and mother that I copied from File A to File B. It asked me if I wanted to add a Marriage Event. I said Yes and filled in the date and place, but there isn't a Marriage Event tag listed on the husband or wife. The mother is listed as the father's spouse, but there is no Marriage Event tag/fact. I tried to add it manually, but couldn't. (I clicked Add a Fact, Marriage, but a duplicate of one of the other events appeared (BDBu, etc.) instead.
3. Since Sources weren't copied over, I'm guessing Notes wouldn't be copied either.
4. It'd really be nice if the Media was copied over as well.
