The version of Reunion that's included in the v2.3 catalog is wayyyyyyy out of date, is already unsupported by DLPB (who was never keen on it being in the catalog to begin with, and has since released 3 major updates to it, the last of which makes it completely incompatible with 7H style modding), and is also being dropped by the 7H crew in the v3 catalog coming out soon.
