Must've misremembered, thanks!

Thanks for your message, I wasn't aware of the junction=roundabout tag as I don't recall ever seeing it on existing roundabouts. Second one is my mistake, other roundabouts in this changeset were correct and I must've missed this one.

I have time to map it now if you'd like, and you can check it out/revise it if needed tomorrow.

I believe the western part of Mount Ridley Nature Conservation Reserve is now a permanently protected area under Conservation Area 26 - Mt Ridley West (including adjacent Banda Bail Reserve) as of 2025.

Ah yeah, missed that, thank you!

This changeset broke the relation - I'll try to figure it out
