Osmose false positives for waterways connected to coastline

1

In Osmose, almost all rivers and streams in the Philippines connected to the coastline are erroneously tagged as Unconnected river or wrong way flow and Unconnected stream or wrong way flow.

I already reported the bug in Osmose backend, and got a fairly vague response. Upon inspecting other countries' coastlines, there are no similar reported issues in Osmose. Is there something wrong with the multipolygons/relations of the islands that show these false positives? Can someone check what causes this in the Philippine coastlines but not in any other country?

I guess the "vague answer" hints that it's indeed a problem with osmose-backend.

I think that, as in other application consuming OSM data, coastlines are updated separately, because it's a really resource hungry operation. The coastline of the island I've checked was updated in June, the river days ago, maybe osmose doesn't compare objects from the same date...

Hope this will get resolved soon, but I'm sure you don't have to worry about it.

Regards.
