We lost our All star point

For some reason, My WOW-classic all star point of Icecrown Citadel lost yesterday, it still show in Logs of every Kill of Boss but no longer be calculated for Rand, this is my character link https://classic.warcraftlogs.com/character/tw/%E5%8F%A4%E9%9B%B7%E6%9B%BC%E6%A0%BC/%e6%b4%9b%e9%98%b3%e7%9d%80%e7%99%bd%e8%a1%a3
And it’s not just about me, some character in my unit face the same promble too
