At the end of the episode Geordi and Capt. Scott use the Jenolen's shields to keep the main entrance of the Dyson's Sphere open to let the Enterprise out. Geordi tells Picard that the Enterprise won't be able to go around the Jenolen, they'll have to destroy the Jenolen and get through before the doors close. The must fire photon torpedoes at the Jenolen and transport Geordi and Scott out before it blows. They do so and make their escape. The only problem is how did they transport Geordi and Scott through the Jenolen's shields? They were up the whole time, and they transported before the torpedoes hit, so they didn't take out the shield first and make a split-second transport. Unless I'm mistaken, which I'm not, it's been stated on many occasions that transporters cannot transport through shields.
