Don't know if this has been reported yet, or if it's even an issue. Before the latest patch, I remember Heroes who were operating standing over the module, somewhat aligned to the center. Since then, Heroes have been off to the side and getting covered up by other Heroes in the room. Heroes like Elise, Gork, or the Warden (for example) would end up covering the smaller Heroes, giving the illusion of a Hero missing. Just my thoughts. Maybe it's just me being picky.
