Katie Hannon TF. Last mission. NPCs can get stuck in the geometry.

Fortunately, it wasn't Katie. Just one of the NPC. I think this means there is a hole in the map.

 

She is quite stuck and never popped out.

Not saying it's not a bug, I'd love for this to get fixed, but at this point I just consider it life with flying NPCs, like Scirocco when you get him as an ally in DA missions.  The good news is, if you have a teleport of some sort, even Assemble the Team, that will get the unstuck (until the next time they get stuck).
