Quantom X

Plot hole: On the first level when the giant truck comes out and tries to run Sonic down, if Sonic slows down, the truck slows down too, even to a crawl while still chasing Sonic. But its mission is to hit and flatten Sonic. No reason to have it slow down because the player does.

Bug: In one or more of the water races for the Chao, there are some large red crabs moving back and forth on the side lines. When they move to the left or right, their claws raise up, and then they lower the claws. But as soon as the claws lower, they instantly vanish and reappear above them again and lowering once more.

Bug: There is a pillar with a ledge over looking the pool in the Hero Garden. On this pillar, there are 6 columns supporting a roof. Sonic characters can walk right through or stand in the same space of the columns, as if they are not even there. Yet the roof is supported by them.

Bug: In the Chao gardens, Tails can fly right through the GBA shaped top of the Chao Transporters like they don't exist.
