I downloaded all members in JOSM and saved to a file, and then wrote a 
script that checked that all nodes referenced from ways existed. 
Surprisingly I didn't find any references to non-existent nodes.

Except from that, I've cleaned the relation's ways from duplicate nodes 
etc., so there's no validation errors from the validator in JOSM. 
However, the problem is still there.
