Please do not report missing/broken cities in this category any more. This effort has been moved to a spreadsheet to make things more manageable.
Head on over to Missing/Broken Cities Tracker to report issues and/or help us in the effort to fix data in OpenStreetMap. Please provide as much information as you can.
Paired with this, there’s now a new Slack channel for us to chat in. This will hopefully be easier for chatting about problems, how to fix them, etc.
