I'm trying to build a custom multiple star system.
Used BET Tuc, Castor, and NU Sco exports as my base of reference. But the Barycenters don't resolve and the stars end up randomly scattered in the universe.
Tried following the Creating A Star guide and the Barycenters instead end up as hypergiants also scattered randomly.

Could you upload both your catalogs for planets and stars folders?

Sure

📎 Daiseiryuu.sc 📎 Daiseiryuu_System.sc

@fleet gyro the main star barycenter doesn't need to be declared also in the planets catalog, in fact if you do that SpaceEngine counts 3 objects around a barycenter which is seen as an error in the se.log file, so this can be removed from Daiseiryuu_system.sc:

{    ParentBody    "大星流"
    Orbit
    {    RefPlane    "Static"
}    }```

Right Ascension coordinate RA is usually expressed in hours, minutes and seconds, but SpaceEngine accepts also the value in degrees like in this case.
By placing Daiseiryuu.sc in a catalogs/stars/ folder and Daiseiryuu_system.sc in a catalogs/planets/ folder, the  system seems fine for me and stars are orbiting around their barycenters as expected.
Make sure you don't have other copies of the same system or slightly different systems with identical names loaded in the addons folder, in that case SpaceEngine will try to merge those scripts resulting in possible inconsistencies, that could explain those hypergiants you mention.
check the se.log file for possible clues
