I am just about done with finishing off hard mode, but on number fourteen, and 11, both of them went back to there starting place when I grabbed on, like number 11 went back into that fire temple place inside and number fourteen I killed in front of the steps he starts out on.

In my first play through they didnt do this, was this just a large coincidence?

you mean when they dieing, they dont die on the place where you killt it? nope. not a glitch, just the cutscene where he's dieing is placed on different parts of the area, and the game chooses the closes of one of the area's that you'r killt him in, it is kinda strange when you kill him outside the fire temple, he will die inside the temple. maybe because thats the only place where he supposed to die, and not only the dieing scenes are strange, also when you return to the place to see he's corps, the corps isn't on the place where he died at.
it's all been made that way.

Naw, when im on them both they run to the place where they first started out, in my first playthrough in normal and hard, they just ran around were they lost there armour.

thats just normal too. especially the fire temple one.
