I was wondering if after the fixes you put into Australia, would you be looking at extending the admin level 10 logic further afield?
I was just trying to plot some routes for when I go to Wales in a few weeks and was surprised to find no nodes would be completed. When I dug further I found that the area I will be staying in doesn’t exist in CS. It is admin level 10 and a lot of surrounding areas have been added.

I think in general for UK you have used admin level 8 and this area doesn’t have anything at that level? I know I have previously added to the spreadsheet my home town which is also level 10 so as it had been done elsewhere, wasn’t sure if it was a question worth asking elsewhere?
I guess it is awkward as at level 10 this area probably has very few streets so isn’t a “real” city but otherwise it doesn’t exist at all.
