Plot hole: When Sonic and Tails land on the Egg Carrier, Tails reminds Sonic that they have to go look for Amy. But Sonic never told Tails that Amy was on the Egg Carrier, and Tails was not there to witness her kidnapping, so how could he have known?
Continuity mistake: In Sonic's campaign, after crashing Tails' flying machine you are told Tails is missing, yet when you reach the next action stage Tails is once again behind you.
