I am having the same issue.
I didn’t realize that having the quick-targeting on was resulting in the event at the stage feeling really buggy. I left the instance before its completion and cannot re-enter.
It’s telling me to go find those other people but they only have the leave option.
I’ve destroyed the Kit based off the advice that it would allow me to redo the instance, but now I don’t have the kit and still cannot enter the instance.
I’m hoping there a resolution. I really want to continue the story.
