Thanks for gathering this list! 
My trouble now is that I have to look at every single city to determine which one is correct.
If a bunch of us work through the list at the same time, it will go much faster…
I added a sheet to Missing/Broken Cities Tracker - Google Sheets named “Duplicate City List” that I’ll work in. I’ll delete rows as I work through them, instead of marking them as ‘delete’ and I’ll batch delete rows as they’re filled in by any of you that feel like helping out.
