Poop Deck Dead End?

[Jurassic Fart 1]

During "Intelligences of the Artificial Persuasion," Skipper causes Bosun's minion Poop Deck to be squashed by a remote-controlled hatch ("door" to landlubbers)….
…and (speaking in the third person) player finds himself unable to reach the next objective; there's nowhere to go but back—away from the objective. The compartment Poop Deck had occupied has no levers or buttons to summon an elevator, and there are no ladders, nor hatches that will respond to the Action key.

How to proceed?

The hatch should open up again, after smashing poor fellow. If it's still closed, then it's a bug, I think.

Great. I guess the game's broken from that point forward—it's a storyline mission, not a side mission.

F♥♥♥ing great. I have to start over from scratch via "New Game" option. I absolutely detest this—I'm currently level sixty.

P.S.: I was mistaken; there IS an exit in that compartment.
