The day after the 1.7 patch and Blizzard is sorry to inform everyone that all honor data for the last 24 hours has been lost.
"There was an issue during the Honor tally process which resulted in incorrect collection of Honor points. While we have addressed the issue so that Honor will properly calculate in the future, we regret to inform you that the PvP Honor data which did not calculate for the last 24 hours since the end of Tuesday’s maintenance cannot be recovered." - Blizzard
Good or bad? Well no one likes losing anything. It is good for me in the fact that a lot of people hit AB hard and heavy gaining A LOT of honor. So now I will not have to gain as much to hopefully compete this week. Unfortunately that 24 hour period is about the only time I will get to log in during prime time bonus experience this week.
We will have to wait and see what Blizzard does about this.
