XP Rollback/Lost/MIA??

At least 2 times now my XP has gone backwards within the last week or so. As in i’ve lost a significant chunk of it, both times after I have gained a rank. The next time I come online I’m back down a rank and when I rank again I dont re-gain the unlock because I already have it.

The most recent time was last night/today (10/02-11/02). I completed the monthly challenge last night and was about 5k away from hitting SR116. I completed the challenge, got the 30k and pushed me half way through 116. Then, today I go to app.halowaypoint.com to have a peek and its diplaying me back on 115 with about 3k to rank. I start the game up later on and yup I’m back down a rank again, just like the app showed. 30k down the drain.

Anyone else recently been having issues like this?
