Hi ChonkerStonker,

This changeset added also caused issues with bus route relations. The newly made ways were added at the end of the route relations and you didn't sanitise for which direction the bus is meant to go in, so each bus route was going in either direction of the road for each roundabout.

Also, Highview Road (28640412) (https://www.openstreetmap.org/way/28640412/history) should have been split in two from where it meet with Chesterville Road to properly allow for routes to turn left without going on the wrong side of the road. You can see what I mean here (https://www.openstreetmap.org/way/1305487927) with what I did.

I've since fixed the routing in https://www.openstreetmap.org/changeset/154794621 as well as splitting the road to allow for turning.

You should be able to see both bus routes following their respective correct paths here:

https://www.openstreetmap.org/relation/11189472#map=18/-37.93026/145.06435

I know that this changeset was made before my first comments, but I've fixed at least 2 separate routes today that had issues caused by your edits. This changeset: https://www.openstreetmap.org/changeset/153021217 being another one that had issues with the routes, fixed here: https://www.openstreetmap.org/changeset/154794427. Just want you to be aware.

Please don't hesitate to reach out for assistance when it comes to routes!
