Is it possible to the map icons which are showing other Carbonite-users?
If you do not want to see other Carbonite users positions on the map, try opening Carbonites options to the "Map" page and unchecking the "Show other player positions in city" and "Show other player positions in zone" options.
Ahhhh, the vagueries of the aging mind. Wait.... What was I saying?
