Objects that aren't added to client.screen but are on the map will show up on the HUD as long as they have a screen_loc.
Code Snippet (if applicable) to Reproduce Problem:
mob
icon = 'smile.dmi'
screen_loc = "1,1"
Expected Results:
The atom should only appear on the map at its normal loc, not at its screen_loc, because it hasn't been added to client.screen yet.
Actual Results:
The atom appears in both positions.
