Old posts became Unread again?
Branch in which were migrated posts from old ITRC forum became all unread again.
There was another update for old topics?
I had this already often in the HPUX part, the problem is if a thread get moved by a moderator it get marked for the normal user as unread which leads to this randomized sort order.
And it seems even without any official answer that there is a lot of moving going on ...
