I was doing QA for routes https://tools.geofabrik.de/osmi/?view=pubtrans_routes&lon=-117.31567&lat=34.51586&zoom=15 and saw that an issue may have been caused by you when you split Civic Drive.

Be careful when splitting road medians since this can break route relations. Don't worry about PTv1 routes as those aren't useful and are far too broken, however make sure to fix up any PTv2 routes.
