I am finding this frequently and I'm not sure why. The parents are not listed on MPs. Any reason? I know they are already on the tree, and I hate to start adding more duplicate profiles. Mary
I have found that parental links disappear if you change parents in "edit relationships" twice in succession.
Say you have someone on the tree connected to the wrong parents. You go to "edit relationships" and pick the correct parents from the pull down list at the top. You go back to tree view and realise you still picked the wrong set (easily done in some cases). You go back into "edit relationships" and pick a third set. When you exit from that, your profile is orphaned. This has happened to me a few times recently. I have not reported a bug (except here now!).
