(adsbygoogle = window.adsbygoogle || []).push({}); Just finished the campaign on veteren and I didn't get the 100g achievement for completing it on veteren. Turns out it hasn't recognised over half of my gameplay. I'm mission select I'm only just on act 2.
Has this happened to anyone else?

First i lose 11 ranks online and Now I'm gonna have to go through the campaign again /facepalm
