Guild Wars 2

Event “Save the merchants from the Bloody Buccanner kidnappers” situated in Vindar’s Lagoon, Bloodtide Coast.

The event insists there is 1 missing merchant. Lots of Bloody Buccaneer Kinappers running around and to the south where the wrecked boats are with lots of Penzan Privateers locked in cages, but once the Bloody Buccaneer Kidnappers reach the boats they become invulnerable to attacks. There’s also a cage up in the top of the wrecked boats that’s empty but you can accidentally lock yourself in it and can’t get out again unless someone lets you out.

I was later informed there was discussion somewhere about this event that it’s known to bug out where the last remaining merchant is MIA and the pirates become invulnerable. I haven’t seen it reported here however after doing a search.
