Serious editing issue -- needs addressed immediately.
I was reviewing the family of Robert Thompson McGinnis (G8NZ-7YX). Records were indicating that Robert had at least two wives. Margaret Swisher (KC5W-Z5N), and Lydia Hole (L4P9-4VX). One child was identified as a child of Robert and Margaret. Three (or maybe four?) of the children were identified as children of Robert and Lydia. Leaving at least three of the children with an unidentified mother.
One of the documents for Alexander McGinnis (L4Q1-VWD) indicated that Margaret was also his mother. Attaching that single document to Margaret suddenly swept all of the Robert's children under that one family. The edit should have just connected the single document to Margaret, but instead — it severed the parental relationship with Lydia and all of her children, and migrated 7 children into a relationship with Margaret as mother.
Meaning that the smallest changes right now can produce sweeping, damaging edits to the entire tree. Meaning that FamilySearch right now is severely broken.
