I got all the Halo 2 skulls and the achievement for each individual skull but I never unlocked the “Trophy Collector” achievement. On the progress it says I have 93% complete but I’m pretty sure I have them all. I trust that the problem will be fixed but I just thought i should report it on here because I really don’t feel like getting all the skulls again, hoping to unlock it only to find out it still doesn’t unlock.
