Second bug fix update!

Second round of bug fix:

• The passengers change animation correctly. Before this fix, the animation of the NPC wouldn't always change from walk to idle. When the player clicked on an NPC and selected them to another position, the walk animation continued in a loop even when they weren't moving.
• Passengers who appear in pairs now face the correct direction of walking.
• Passengers waiting in the train station, they are now easier to select.
