The other day I was re-arranging our Leads module setup in CRM, and I removed the Section "Address Information" so I could move the address fields into another section. Then I noticed that the button for Locate Map, which just takes you to Google Maps on that location, disappeared. I have now spoken to 2 support reps, and both have told me that because I removed that section (just a section separator, no actual fields) that button is now gone forever and there is no possible way to get it back.
