Ranking system bugged?

My problem is pretty straightforward… I’m a level 50 player, but I logged on today to find that my lv was set back to level 1. Has this happened to anyone else? Is it just an in-game bug? I still have all the data of previous games and playtime. I looked myself up in halowaypoint and I still have the rank of 6th star which if I remember reading correctly its rank 50. Everything else seems to be in check, it’s just when I run halowars2 on my console, it appears I am rank 1:( “sad noob level status”
so yeah if anyone had any answers and is willing to share that’d be great!
