Wrong forum.
For issues with WoW, please use the WoW forums.
If you think you have encountered a bug, refer to: Report a Bug in World of Warcraft - Blizzard Support
Finally, there is a Customer Support category on the WoW forums… here:
That category acts as an Information Counter… the Blizzard staff who moderate and monitor that category aren’t Developpers (so they can’t fix bugs) and aren’t Game Masters (so they may not be able to fix game issues). But they may be able to provide info on this issue since you say it has been reported by others.
Best of luck in your games !
