This has happened when I am adding people and later realized they are a duplicate (multiple marriages, same mother, same father, etc). When I merged the two people it all seemed okay, until I realized the person who was merged had hints pending. Now the hints are linked to "," and ignoring them doesn't make them go away, and accepting them doesn't make them go away, and trying to delete the null person takes me to the page saying oops, that page doesn't exist. I have 63 pages of hints that are related to 'null' people apparently.
Does anyone know how to resolve this software issue?
My husband and I are 18th cousins which has been part of the problem!!
