Yeah. By way of explanation, there’s currently a monolith bug where none of the normal systems are having their star_id returned, both in latest and in v4. It works in v4 because star_id was made optional in that one to account for the new abyssal systems, but the star_id isn’t present in either route.
According to @CCP_SnowedIn It’s looking like it’ll require a downtime change to fix.
