Losing ranks in the ranked playlist!

Hello 343I, Microsoft and fellow gamers,

Yesterday I was rank 12 in the halo 2 ranked playlist. After a game with my friends I suddenly noticed my rank got reset to 1! While my friends noticed nothing about their own ranks. Nothing changed today, got my rank up to 3, but it is darn frustrating that my ranks are gone. Did you reset a certain amount of people or is this completly new?! My dear fellow gamers, stand up and reply if you had this problem aswell! I hope 343 will notice it, and get it solved. Thanks in advance!

Greeting,

Sv I LB I
