"An Interrogator" for Qeynos Badge Quest South Karana Bugged

[Wolfblood]

Edit: DISREGARD. As soon as I finished submitting, he reappeared. Assumedly just to spite me.

A player abandoned their Qeynos 2 badge kills and logged, so I killed them and took the heads. At the time, I thought I needed the interrogation documents, so I went to the interrogator to get him to repop the guy to interrogate after collecting the heads from the two quest targets. He then proceeded to tell me he was going to hermit house, then walked all the way across the zone and disappeared causing me to lose my quest item that queued him to walk, "Interrogator's Briefing".

Since the first part of the quest isn't very tough, I just went and redid it thinking it would give him time to repop in his spawn location. I returned to South Karana and he hasn't shown back up in about an hour. I suspect he's not coming back. Please assist.

I won't be able to receive another quest item as I'm holding a new one already and I don't really mind that part anyway. Mainly I just want the Interrogator back to continue with my quest. Thank you!
