When a Mod moves a post between boards the Topic is flagged as 'moved' and a link to the new location created. However, the original Topic is still marked as 'unread' in its original board whilst also being available and 'unread' in its *new* board?
Some redundancy here? It would make sense to remove the 'unread' flag in the original location so minimising the effort to read any active topics in the thread.
