Plot hole: When Dr. Hughes is racing to save Allison when he thinks he is Carter from the events that happened in "I'll Be Seeing You" Henry says he is racing for a cliff, and that the cabin was just a hologram. But in the episode the Cliff was the hologram disguising the cabin. Henry even commented in that episode that he did not remember a cliff being there.
Nathan Stark: Good job, Carter... Wow, that didn't even leave a bad taste in my mouth.
Marshall Jack Carter: Wait for it.
Nathan Stark: ...Oh, there it is.

Question: When Jack and Jason go to talk to Todd about MACAA, Todd tells them that they destroyed it in Section 14 pit followed by a nuclear explosion. If it was destroyed, where did the version that is missing from the shelves come from?
