Continuity mistake: When the Alcoholics Anonymous run out of the church, Barney yells out "I can't take another minute in this dome!" and charges towards the dome. In the overview shot, the church is directly behind Barney. In the following shot that shows Barney hitting the dome, the background has changed completely. The church is no longer there and two houses have suddenly appeared.

Continuity mistake: When the dome is being placed over the town, the church and Moe's Bar are shown right next to each other, but later on in the film, when Barney runs out of the Alcoholics Anonymous meeting at the church, Moe's Bar is nowhere to be seen. (00:26:30 - 00:48:30)
