Update - Unfortunately, the problem is still occurring. We're sorry we haven't fixed it yet, and we're sorry it's been 18 days. We're still not sure why there should be a problem with it. We will try to start logging the script we use to generate the News Channel files.

Identified - There's currently a problem where the Italian version of the News Channel is giving NEWS000006. We have determined that it's a problem with how the file is being written. We need to figure out how to fix it.

Monitoring - We have received 2 reports of people getting the DLC finally. We're not sure if the DLC is only importing to people who haven't got the RC24 carpet before, as those 2 people haven't gotten it.

Update - We have fixed a problem with the Gracie carpet DLC on the server, but the problem isn't something that should necessarily fix the DLC and make it be delivered. Please tell us if you get the item. If no one gets it, we will look into it more. Animal Crossing: City Folk DLC is honestly a bit of a pain to work with.

Update - Because of the problem with not receiving the Gracie carpet DLC, in the meantime we have put the old DLC, the RC24 carpet, back on distribution until we fix it.

Investigating - There are currently some problems with the "Gracie tile" DLC that was released for Animal Crossing: City Folk. First, the problem was that it wasn't being distributed on the servers. We have heard no reports of anyone getting the DLC.

Further inspection shows that the wrong message is being sent out for the Gracie tile DLC for English (in the US). This doesn't explain why it's not working as that's a separate problem. We will continue to investigate.
