What is happening:
When multiple quests have the same destination, multiple quest markers will appear there and overlap each other.
What should be happening:
There should only be one quest marker.
Steps to reproduce the issue:
The easiest way to do this is to get multiple quests that require you to travel to the same map, many quests require you to go to Ponydale or Cantermore, so just start a few of those, and go to the area where you would travel to the map the quest requires you to be. (The train station, the airship, etc.)
