There were some islands in this channel some weeks ago. Assume they have disappeared in the transition process while moving objects from coastline to other data layers.

Thanks for the answer.

Shouldn't the question be: "What happened to the islands?" or "How to recover these islands?". What is the question after all?

Opened a part of the area and saw that the former islands still retain only the "natural=coastline" tag, and the riverbank's ways are now part of a multipolygon relation with "waterway=riverbank".

What has to be done is:

  1. Remove the natural=coastline from the islands;
  2. Add the island's ways to the multipolygon relation;
  3. Add the role "inner" to the islands;
  4. Optionally add the "place=island", mainly when the island has a name.

Thanks for the (edited) answer. The described case is just an illustration of a systematic error source when people are moving objects from class to class (missing objects and wrong class). These errors are never detected by any OSM error or change detectors today. My intention was to bring this situation to the OSM experts' attention. Maybe I did this on a wrong place.
