Event is called “Protect Pinion Pass from destroyers” (right next to Winterthaw Waypoint on the lower east side of the map) or something around. It takes 12 waves of destroyers to finish the event, but problem is that the last wave is not spawning at all. Been waiting there like 15 minutes for the wave to come, but it didn’t happend. Maybe it was a single accident, bad luck, but maybe not, so here I leave a topic, check it out, let us know if someone else got same problem with this event.
