Hi I just started playing Lara Croft and the Guardian of Light with a buddy. He already finished the game but wanted to try coop. So we started and all was fine.

Then we got to the first Challenge Tomb. The problem here was that there were no power ups here... as in no reward for doing the Challenge Tomb. Now we figured that it was because my buddy already did the tomb, but I had not gotten the corresponding upgrades. We tried doing it with me hosting rather than him and I also tried to look at it alone and discovered they were not in there either.

Is this suppose to happen? Did I miss something?
