can't finish the adventure due to glitches

Wondering if anyone else got these and have some advice:

• when I'm loading into a portal, be it the adventure or Pirate's Life, I suffer a server desync (Hazelnutbeard) every time. Without fail. It allows me to rejoin back into my ship but due to my ship already being on the other side of the portal I cannot complete the "Arrive at the Sea Of The Damned" deed.

• after the final dialog between the Pirate Lord and the Dark Brethren, when Merrick is teleported away, you're supposed to be black-screened into the portal tunnel for a cutscene. I am not. The Pirate Lord and Merrick disappear and I get stuck in the Twisted Sea Dog Tavern until I quit the game, which needless to say cancels the Adventure.
