Batman Arkham Asylum Grapple Glitch

[maD]

So I picked up Batman AA a few days ago and have been playing fun and all but right now im stuck....

Right after the part where I go to the batcave and made the formula to reverse the bane poison joker is trying to make his army from this is also when you get the ultra batclaw and ivy's plants take over the batcave and I have to glide from island to island and get back over to the sewer but im stuck at that spot and it seems that the grapple isnt wanted to work and i've tried restarting from check point but it just bring me to the same spot.


Anyone know a solution or fix?

Yea, hear you go.

This is right after you glide into the cave from the outside cause ivy's vines took over the batcave.

this is the place I need to grapple to get over but its glitched and wont let me.
