I'm not in Haven anymore, which is why I'm troubled D=
I've been in Skyhold for quite a while (already customized it, built a garden, moved on the main quest, got everyone talking to me and giving personal quests, etc). There are no more options of new things to discuss, just saying goodbye - and there haven't been new options ever since I've first seen him in Haven and exhausted his dialogue wheel in one go.
At first I thought it was just something normal, but I've moved forward with everyone (already started romancing Josephine and Dorian, for example), which is why I think it's so weird that he hasn't even directed me any comment at all. I've had new cutscenes with every other character (even Cullen!). But Iron Bull won't even bat an eyelash when seeing me, despite the fact that he should at least comment something about the new place.
