18463	changeset download: only download modified members of relations	skyper	team	"==== What steps will reproduce the problem?
1. Have a changeset which includes a least one relation with many members
1. start JOSM with a changeset as argument or ""download current version of changed objects"" of a changeset through changeset manager
  
==== What is the expected result?
Only object which where modified in the changeset are downloaded

==== What happens instead?
Modified relations are completely downloaded including all members.

==== Please provide any additional information below. Attach a screenshot if possible.
If there are some bigger relations included, you do not find the real content anymore as it is hidden by all the other unmodified relations` members.
Getting rid of the unwanted members though filtering/purging is much more difficult than downloading incomplete members later on.

In my case I had ten relations with over 2000 members and did download thousands kilometre of unneeded ways.

Think the behaviour changed a while ago (last two years) but I am not sure and snapshot r14760 is the oldest one I checked which shows the same behaviour.
