Jack Quicksilver disappearance in Core City

[TΛPETRVE]

Jack Quicksilver disappeared after half of his questline in Core City, despite fulfilling all 3 assignments flawlessly. Dunno if this is a bug or simply an oversight on my part.

Did you manage to report all three quests to him and if so, what was the last thing he told you?

[TΛPETRVE]

Don't quite remember his words, but I got payment for all 3 quests, and he was satisfied.

OK, same with my current character. Usual proceedings done, Jack says "Now we wait..." and disappears forever.

Note: I finished all 3 assignments in one go and cashed them in at once. The only time I was actually allowed to proceed with the Azif quest was when I did the 3 quests one by one. No idea if there's a connection.

EDIT: Tried it several times in various orders, to no avail. It seems the quest is completely impossible to complete under certain circumstances.

Have to bump this as I am experiencing the same issue, he told me "Now we wait" and then disappeared.

From what I gathered you can circumvent the issue by simply not accepting his delivery job at SGS, which seams to be what bugs his questline in Core City.
