In this area here near talegaon
(Also any way of attaching frame grabs?)
Everything seems ok to me in this area, at all zooms, viewing with the standard osm display map. I have known errors with coastlines to flood the map with blue inland, but it is usually local. So I suppose it could occur with lakes as well. How far out can you zoom out and still see it?
There was a problem with the tile server that was in use in Australia, see https://lists.openstreetmap.org/pipermail/talk-au/2019-June/012719.html . I’ve no idea what tile server you’re using, but maybe it was the same one?
