Guild Wars 2

I cannot advance any further on 2 different characters because of npcs getting stuck or scripted events not triggering.
The 2 missions this is happening in are A Grisly Shipment and Ossuary of Unquiet Dead.
I’ve tried restarting the mission but the same exact problems occur.

I did “A Grisly Shipment” for one hours ago on my Asurian Mesmer, although I had to run around with Maeva in her Golem suit a bit up from water until she would give me the offer to use one of those Foefire bombs to use where the dead bodies where on that ship. I think it took 5 bombs to trigger next step for the story to continue.

Your attack party (NPCs) can be a bit tricky to get a hold on during fight as they seem to disappear out of sight, so it might be that you need to run from one side of ships lower deck to the other to be able to see them again (they follow you – look up to see a green star if they are above your deck level) and to get Maeva to offer you her bombs.
