ive done all the cyberpschyo missions and im at end game on the main quest line

Does returning the gun she lost count as a gig? Does she give any hints if you go talk to her at her office? I'm still in Act 1 at a low level so these are wild guesses.

Returning Skippy is a gig (or a side job?), but does not count towards the 22 total. And she remains disappointingly closemouthed when you visit her in her office.

Good guesses, though :)
