This is happening to me, I went from 13-15, then it reset, then went from 13-16 again and it reset AGAIN. So I'm done playing the game for now until this issue is resolved. Really pissing me off.

I'm not stuck anymore..I noticed theres a Rank 10-11 and EXP started moving and I ranked up and got the weapon!

Everythings started working again about two days ago and my progress is all back. Thanks EA for fixing this.
