I forget the name of the tomb, but it's the one where you have to throw the yellow canisters onto the cage to lower it and then run down, throw one off, then run back up and jump on as it rises. I threw on 3 initially, which lowered the cage. I then found that after reducing the number of cans on the cage down to 2, 1 or 0, the cage stayed on the ground, and did not rise as it should. So I decided to try everything I could, and found that if I chucked on all 4, and then threw one off, THEN it rose and I was able to complete the tomb. It took a few tries to get the timing right, but the 4 cans\3 cans technique did seem to consistently operate the cage. Has anyone else encountered this?
