Re: Mass Effect 3 - Hanar Diplomat

You could try doing something else (in a different area) and then going back to the Docks Holding Area.

Example: I had "Citadel: Barla Von" bug on me yesterday...

When I arrived on the Presidium I clicked Von before talking to Liara, so that when I went back he wouldn’t talk to me. I left the Presidium and did something else (like going to the Spectre firing range to test weapon mods) when I returned to the Presidium I was able to speak to Von without issue.
