I'm stuck in the cave with Harry and Dumbledore. I've released/moved the apparition ring that was held by (what looked like) bicorn horn. I went to get into the other apparition ring next to where it was (the one that should transport me to the one I just moved), but both Harry and Dumbledore just stand there with a ring of arrows around their wand. I'm pushing the button that should make them apparate, but nothing happens except for the ring of arrows. Is this a glitch or am I doing something wrong?
I jumped on the floating rocks back to the beginning but I'm not sure how to get out of here now...maybe illuminate all 3 lights around the darkened doorway, but how? If i try to take the light from the first little island, it closes the gate and doesn't allow me to jump back across to where the doorway is?
