Not sure when it ends but the same happened to me…
I’m pretty sure you got the xp ban for just gaining too much xp in one day. Which I as well just got. It’s not like Reach where is turns off in the next day so my guess is it’s a 24 hour ban and if that is true I’m going to be pissed because that is just stupid.
If they don’t want me to play the game then fine I won’t
