Markers on Map Appear Black

**As we add banners to the map and more people pick up the map slowly the markers on the map have begun to turn black.  It's possible that this has been happening since the named banner was placed down, but I'm not sure and it's possible it happened before.

Also there are currently only 2 people logged in and yet at least 4 people holding the map are still visible on it despite not currently being playing.
