Just a thought, but the current Live version, 5.0.4.16016 has been on Beta for about 5 days. They possibly got started on coding HB then since it's only a week downtime. Just remember, it could be worse and not have the bot till Mists hits live.
Also, to the person saying PQR worked the moment server's came live. Again, 16016 was on Beta for almost a week. The live version of it had the exact same offset's as what was on beta. That's why it worked on day 1.
What I do hope that comes out of this week downtime is possibly that HonorBuddy finally get's offset's for Beta realms so that profile Developer's and the like finally get time to code their profiles. I mean, if the program is finally getting updated to work with 5.0.4, it should also work with the beta, with the erroneous error every now and then on Beta itself. But as stated on WoW, everything is coded now, most of the work being done is Balancing the classes and fixing the occasional problem that arises.
