Quest Issue: Shackle quest #6 - Shackle of Steel

[Vexxed]

an iksar master in TD. Master Rinmark.

Upon turning in the Pebble Filled box I was rewarded with the Shackle of Bronze.

There is a line missing from his speech at this point.

"Alas, there is no time for celebration. I need your help in rescuing a [student] of mine."

Student initiates the next shackle quest. Shackle of Steel.

He does not respond to anything with "student"

Ie. "What Student?"
How can I help you rescue your student?

Nothing works.

Is this quest simply not in the game yet?

The shackle of steel was my main motivation! hope this is simply a bug and not the case of being not implemented yet. The work and time involved to get to this shackle is insane, so many hours, actually days.

Thanks for looking into this!
