I was at about ~800/1000 Infamy Points, then I ended up hitting 15.000, thus resetting my Infamy Rank. This lead to my progress going back down to 0/1000, and regardless of how many Gambit matches i complete (win or loose), I'm stuck at 0/1000. I've done a bit of Gambit after the reset, as I'm currently at 828 Infamy Points. So, something's bugged if you reset your Infamy Rank while on this quest. PS: Haven't tried abandoning and reacquiring the quest yet. EDIT: Just tried abandoning the quest, reacquiring it, and winning a Gambit match. Still at 0/1000.
