Got to Tier 2(500,000 XP without dying) and watched the achievement XP count go up, then at around 430,000 XP I got a phone call and died , lol, silly
Well I then decided to be safe and rack up the 500,000 needed , like a kitten, this time the count stayed at 430,000 ish and never reset or moved. I managed at least 3 full level 80 levelling(254,000 each) .
So, is this a bug ? as I managed over 3/4 of a million XP without dying ,and never got the achievement ?
