I followed the steps on wiki- talked to eieden, specified investigation, then said the biology wing or whatever its called. But then where do I get my belt? Talked to the guy who runs preseveration, the armory chick, all the merchants in investigation, all 3 branch heads, and there was no new dialogue about getting my belt. Do I get that later or did I need to say assistant investigator rather than full investigator or something?
Edit: If I didn't choose the right option with lydia am I screwed out of my belt? She has no dialogue about investigation and I can't recall what option I chose because RAF 13 maybe me take a weeklong break from the game.
