I literally can't progress the faction main story, because a boss is not spawning in said room. I need to "Defend the Silvenar", but the person I'm supposed to be defending him from decided to take a holiday. Earlier today there were around 20+ people in the same room, trying to do the same quest, to no avail.
I've tried restarting the PS4, which did nothing. I don't know what else to do, other than wait for a fix. How long could that take? I want to progress the story along.
