Character sprites decouple from movement on loop seams when edge of camera is near map seam

[felixjones]

Tough to replicate.

On a looping map, when a character is moving across the loop seam: if the player enters the ship or boat it will sometimes cause the character sprite to decouple from its internal position (_x and _realX become different).

Corrects itself once the sprite animates back into its correct position.

Changing the move-route "distance" algorithm for looping maps does not seem to have fixed this.

Re-identified issue, seems to be related to looping map seams and where MV puts the character graphic.
