I'm playing on xbox360. There seems to be a glitch on prepare for battle. While scaling the spire, where you have to drop down the rock face and then jump across, the jump across fails every time. There seems to be only one spot you can attempt the jump from and every time I try the jump Lara just drops off the screen (you don't even see her fall) and then it automatically reloads the checkopoint. Is there something I need to do before I can achieve this or is there a glitch in the game preventing me from continuing?
