One of the reasons why the read-only downtime between Bungie.net and Bungie.next took a while was because we wanted to port the history of our chatter as a community over to the new platform. This is still being done. If you are looking for full reply histories for older topics, you may see some holes in the conversation. They will appear over time. There was a lot of chatter to bring from one place to another. We'll be doing it in batches.
