Live Long and Prosper Old Man Cho not showing up

[Exoltic]

I was doing the "Live Long and Prosper" quest on my Warlock, but it seems to be bugged. I was wall climbing up with Jinah(?) but my sprint ran out so I fell. I waited for the bar to fill back up and climbed again, but Old Man Cho was no where to be seen.

I have the same issue. How did you solve it?
