What can I do if the group finder is broken and the daily NPC is missing?

Try checking again after reloading the area or your character, but treat that as a basic check, not a guaranteed fix. If the NPC is still missing and the group finder still won't work, waiting and trying again later may be less frustrating than repeatedly attempting the same steps.

If it keeps happening, send a bug report with the event daily name, where the NPC should be, and what the group finder does when you try to use it. Those details make the two problems easier to distinguish from a general report that the event isn't working.
