I hate to be the bearer of bad news since I know you guys are busy fixing several other bugs since game launch; however I think I found yet another. To make things easier I figured I would make one topic to not only discuss my own issue involving completing challenges without gaining the points for them, but also so others can post their own issues in one location without creating a bunch of new topics.
Just moments ago I completed the “This Is Going To Hurt” challenge with 2hrs 10 min remaining of the challenge. Anyone familiar with it will know that it consists of completing any mission on Heroic or harder with the Famine, Tilt and Thunderstorm skulls turned on. So since I planned on once again completing the game, only this time on Heroic; I decided to start from the beginning. I made sure these skulls were activated, started with the Prologue then went through the Dawn mission. To my surprise when I completed the mission and checked Waypoint it showed that the challenge was not complete. Thinking that I might have mistakenly done something wrong, I checked the Waypoint game history, which confirmed I had all settings correct for this particular challenge.
Given that I cannot preview and record campaign history for upload in the theater, any admin will be able to check my Waypoint game history and confirm this. Thanks again for investigating this.
