In the "multi-staged" dungeons Like Blessed Crucible, Tempest Island, Blackheart Haven etc etc, whenever you enter a new "sub-area" with a "mini loadscreen" at the same time as your group mates, the blue health bars on top of their heads fail to load.
This is rather bothersome whenever I am playing as a healer.
I avoid it by waiting for their health bars to disappear from my screen after they activate "enter", before I activate "enter" myself.
Not sure if anybody else gets it.
