Nostalrius Begins - Quality wow vanilla realm (1.12)

Ok, first of all, sorry if I'm wasting your time.
Second of all, I don't know how to use the bugtracker, I created an account and everything but it's really not user friendly.

Anyway:

Today I was doing Cortello's Riddle
And I was at the second step so I was in Dustwallow Marsh and I clicked the scroll after a Dwarf did (I'm Guìnness, tauren shaman).
The scroll gave me 5k exp but no followup and I guess that's a mistake.
It should give a followup and after that a 14 slot bag.
After I clicked the quest log kept opening and closing very fast and then I could not click the scroll again.

I completed the stage exempified in the picture in this page:

let me know!

I completed the entire chain yesterday.

Try abandoning the quest and click the scroll again.. Might work.

Are you the appropriate level for all steps of the chain?
