Specific vine wall isn't graspable

I'm in the Foundry, trying to get to the second Heartstone. I seem to have run into a game breaking bug though, and would like to know if I'm missing something, or if there's a workaround.

When I get to here:

I need to run across the small gap in the vines. The problem is, Death can't grab the vines on the other side for some reason. He treats it as a normal wall and just keeps running, then falls off the end forcing me to climb back up.

I know that it should be simple to do, because I found someone doing it in a walkthrough video.

I'm tried at least 10 times now. I've tried running across the top to make sure he has time to grab before falling. I tried dropping down onto the pillar and trying to wall run from there. Nothing works.

Does anyone have a solution to this? This seems to be a required part of the level, so If I can't get around this, I'm hooped.
