I don't know if you can go out this glitch, but you can try reloading another save before, or using one of autosaves game made at each chapter.
tried the auto save many times this is only happening at this 1 earth healing point (queen tower) no place else have i encountered this problem.
i fineshed it in ps2 all i did was just running on wall and the monster made a path for me to his head ....but i think its the dvd's problem !
ps2 ?
the latest prince of persia ?
