I don't know if this bug is reported already, but:
If I try to attach an existing profile as a parent or a child to another existing profile, if there is any kind of error message (such as too old parents or wrong generations) or just a warning (such as birth year before 1000) it is impossible to complete the connection.
The 'continue anyway' button does nothing except close the warning, and the 'proceed to connect child' button only reopens the warning.
