Flight suit and MK II Tip set not unlocking upon completion of collectibles. Xbox360.
I've collected every collectible in the game, the progress page shows I have 100% for everything. When I picked up the final artifact, I got a message getting achievement, along with messages saying that the Flight Suit and MKII Tip set were both unlocked. When going to a bench and suit changer, neither show up. When I go back to the location of the final artifact at the end of the game, the artifact has changed to a normal item... which is what happens to all collectibles when you've collected them. The only thing that I can think of is that right after I got the final collectible, I died, saved, and exited. I really don't want to have to go through deleting my entire game and starting totally over on everything just to get these unlocks, but I am a completionist... and I really want these unlocks! Please help!
