I loaded a game in the Inn, while the barkeeper Dengler and Lord Harond was having the scripted conversation. I take it you're not supposed to be abled to speak to either while this happens (didn't try speaking to Dengler, but Lord Harond wasn't responding)

 

While they were talking, I went to the bard Sid and spoke to her. Left the conversation there and now Lord Harond is stuck at the bar, not responding. Can speak to Dengler.

Leave the Inn and come back you should be able to talk to him.

 

Wrote it up as well.

You can also go upstairs, then downstairs and he'll spawn where he goes after he has talked to Dengler (otherwise he's just stuck by the counter with his guard).

Also, you can talk to Dengler (that's how you reproduce this bug), but you can't talk to Lord Harond, during their argument. Dengler should get the same temporary locked conversation code like Lord Harond is.

Unless....

Idea:
- If interrupting Dengler & Lord Harond's conversation, get reputation loss (Lord Harond gets angry with you, maybe) "Who do you think you are!?" kind of deal.

P.S. Lord Harond... Lord Hardon (couldn't resist) xD

There are some other points where NPCs are talking to each other and you have to wait until they're done with their conversation to talk to them. As others said, zone out and zone back in works for Lord Harond.
