To make it short and sweet: Something that happens a lot lately in Fractals is the Checkpoint button (that appears when you die) seems to disappear (and MAYBE) reappear quite often. It’s not because the members were out of combat, it just seems to do so.
It’s also not happening to just myself, in fact, in a group I was with, the other members could not tele to the nearest checkpoint at all. I was the only one alive and clearly out of combat (my health was regenerating) for several minutes.
