Someone had mapped a ton of First Nation areas in south-central BC with absurd place=suburb nodes. I went through each one and reclassified them more sanely based on the number of dwellings, with the vast majority becoming place=locality due to the lack of any dwellings. It will take a bit of time for the lower zoom levels to re-render, but then the visibility issue should be resolved. It's already much better for zoom 13+.
