I don't think Multiple Births is a "known issue" but rather a feature request --Ratatosk
But if it isn't a current feature, how can there be a known issue with it?
Noah replied in forum thread "Currently we do not have any special indication for twins or other multiple births. Obviously as a less than usual family relationship, multiple births are something we should expect to have full support for in the future." --Ratatosk
