I saw in an amv that Lucy drew a map of everybody in Fairytail, I'm guessing that I wasn't paying attention in that episode or I was doing Landry and didn't catch a glimpse of it. And I think she was doing the map to try and find everybody and bring them back into the guild? I don't know..
Perhaps you are talking about Episode 276: Challenger, this is after the Fairy Tail Zero arc.
After the guild has been disbanded, Lucy is still keeping tabs of her guildmates's locations that why she have that map
