The Good Instincts challenge (Instinct Cancel 5 times during combos) started roughly four days ago and I can't get to unlock it. By its description, it seems pretty straightforward: just start a combo with the Instinct meter full, and then, after a auto/linker/manual, press FP + FK.
I tried this with all characters, in all game modes (VS CPU, 2P, Survival, Ranked, Exhibition), and even though the game is tracking Instinct Cancels just fine (I can tell it because "Fight Title Completed" messages pop up for 5, 10, 25 Instinct Cancels, and so on), the challenge won't be met, and progress is stuck at 0%.
Xbox Support at Twitter advised me to re-install the game and its add-ons (in my case, it's the Ultra Edition), but this didn't change matters.
In fact, it seems that no one is able to meet this challenge. Achievement and challenge tracking Web site TrueAchievements reports that among 7,399 tracked gamers that own Killer Instinct, no one got it, which is rather odd. A few people also reported this on Double Helix Games' bug reporting thread and elsewhere.
If this challenge is actually glitched, will it be fixed and its time frame extended? Only 72 hours remain.
Thanks in advance.
