If you have more information about a specific marker, use that coordinates to help me locate the marker. You will notice coordinates inside the popup of the markers, these coordinates are the ingame coordinates. You can add a name and a description to your markers, as well choose the marker icon.
Markers content will be updated with more details! New option to export/import and clear the markers you added. If you had markers on the map with the previous coordinates system, they will be automatically converted to the new one. Map coordinates now match ingame coordinates. Markers shared with you can be added to your markers. Now you can share the markers you add, just add a marker on the map and copy the marker link. All map markers have a link now which will direct to them if visited.
