When creating a descendant chart of 6th generations the children in the 6th generation were connected to one line and the line was connected to each couple of the 5th generation. RM9.03
Confirming this issue has been reported to development.
Also, when generating Descendant charts with Best Size Fit to Chart unchecked… locks up RootsMagic for me.
When the charts are created as an png image file you can edit it. I found all the connection lines w4ere correct only they were on top of each other.
