Hi there,
I collect cards with the default flag and got them all for season 3, as complete as the list was when s3 came about and the XML file was generated: https://www.nationstates.net/nation=the_colonial_buccaruu/page=deck/collection=55311/?filter=season-3. As by that file there should be 33047 cards of s3 with a default flag (svg, jpg, png) minus 4 (3 nations which got deleted and Kractero who somehow changed flags after the XML file was generated). As you can see, I ended up with 33793 cards, about 750 more than expected!
However, mods can change "offending" flags from user-uploaded to default flag, like e.g. https://www.nationstates.net/page=deck/card=3162760/season=3 on "future back problems". I vaguely remember that flag showing a healthy young lady, now it's a default flag that is unknown to the XML file.
My question now: Is there a list of changed flags somewhere or are there no records kept of changed user content? In the moderation forum I didn't see any such list, single cases at best.
