Both of those Great Lakes have disappeared from Open Street Map and have been missing for at least 24 hours. UPDATE: all, some or none of those two lakes are visible now at different zoom levels. |

The relations that define the lakes were broken during the refresh of the zoomed out tiles, so the lakes didn't render. That refresh happens once a month or when a new version of the style is deployed. The data has been fixed, the tiles just haven't been refreshed yet. (tile update frequency per https://lists.openstreetmap.org/pipermail/talk/2018-August/081233.html ) |
