Missing bus line 915

I’ve noticed that the buses file coming from this link: https://api.transport.nsw.gov.au/v1/gtfs/schedule/buses
is missing a line.
line number: 915
agency: Transdev NSW
it used to have this route_id: 30061_915

I’ve noticed that it does exist in the ‘full_greater_sydney_gtfs_static’. but we’re not taking the lines from this agency from this file, but the other buses file.

Is there a reason it’s missing?
Will it be put back?

Thank you very much
