Alexandrite Map question

[Gormogon]

There's 2 ways to get a map.

Daily quest (limited per day).
Myth (800 myth per map)

Edit: You get straight up Alexandrite from Fates if you have your animus equipped (very low chance to drop)

If you do the alexandrite map in a party, is there a chance that someone else in the party will get the drop? Or is it set up properly so that the owner of the map will always get it?

Seems to be only for the individual, which is kind of surprising since all the methods to get the maps requires a group.
