Seems to me, since Bioware closed their social network is the reason that many of these new wardens won't upload to the keep is because this is where your character was uploaded too. They have since closed this website and player profiles with their characters is no longer available. New wardens are not showing up and some people say it's because of the console key being toggled. I disagree because I've never modded my game, nor used the console. Hit the key by accident, yes most likely. Our wardens were uploaded to the Bioware Social Network which is no longer available. It makes sense then, Wardens won't show up any longer because of the closing of this website which the Dragon Age Servers were connected too, and your characters uploaded to this website for storage. This only seems to happen with with Origins characters yet, DA:2 characters will upload with no problems. This could also be due to the disk check issue they've had all along when a player re-installs the game. I've had numerous issues with the re-installment of the game on a new pc. This is a problem that they never fixed with the original game. They've always known about this problem and have known it all along, they just won't fix this issue which has been ongoing since 11/2009 when the first game came out.
All you can do now is create a world state, change the name and photo to your former warden and import into Inquisition. So all of hundreds of hours we've all invested in playing Origins and DA:2 is no longer viable and no record of your character any longer except in your own games and you'll have to open each character and check your journals for your decisions.
I don't have a twitter account but someone needs to ask Bioware about this.
The keep when it first opened worked just fine and synced with your player profile on Bioware Social Network.
Once again another *uck up by EA/Bioware.
