I've played AC:B twice now and this part of the game is becoming extremely infuriating. I'm on the 6th Shrine of Romulus (In the Vatican) and I'm chasing after the Cardinal. The chase has just started and the Cardinal has used a lift to go up where I must follow.
For some reason though, rather than jump from the wall to the wooden platform, Ezio wants to do everything else. He'll jump down, he'll jump to another wall, he'll not move, he'll burst into song and tap dance for infants, but he won't jump to the platform. My last playthrough took me around 40 re-starts before he got the diea and I'm currently on 18 retries and I'm starting to get annoyed. How does everyone else do it?
