Which scene in a movie/series do you think didn't make any sense to the plot ?

In episode 17, when Commander Taggart is about to escape the neutron field in the omega-13, he used the auxiliary of deck B... But in the next episode, the schematic shows that deck has been totally vaporized. I was just wondering, do you think that's a continuity error, or do you think there's a justifiable reason for it?
