Irvine is seen to shoot Sorceress Edea from front-on during the parade sequence, however moments later, when Squall drives up to her float, the float is facing directly away from their shooting position. Besides the obvious change of direction in the way the float is facing, the backing of Edea's throne would have made shooting her from that angle impossible.
The first time I noticed this one back in the day, I began to laugh hysterically.
