After jumping to a room, it doesn't matter how many different scans are made, after thoroughly searching the message base (except for the most recent 1 message issue that seems to be going on right now in a few places), the primary prompt always drops back to the last room jumped to. After a scan without anything being available, or after everything is read, the sub-group or room should be reset to Lobby> if restricted, or whatever is sub-group 0 if in a different message group in a non-restricted session (which is still awaiting a lot of work for full implementation).
