I click the icon, it tracks me on the map, I close it, and when I next open it, tracking is turned off again. I don't think it did this before. Using latest version.

This is probably because I introduced the option to remember last browsing location.

Need to decide:

• Should player tracking status be remembered for separate atlases? (i.e. when switching between 2 atlases, where one has tracking enabled, and the other disabled)
• Should the server remember it or only the client?

Use cases:

1. Most common. Player only has one atlas, checks frequently to see where he is going, tracking is on most of the time.
2. Player has 2 atlases: A for navigation with tracking on, and B only has the destination explored (by someone else, or given as part of a quest in future. The terrain may even look different.). He would look at B to see if he has reached the destination. B would therefore need to always show the same location, and A should track the player.
   This configuration should be remembered on the server, but can't be part of AtlasData, because other players might have clones of this atlas.

For now player tracking option is simplified, but this issue will have to be considered again in future.

a7edbfb fixes this from the looks of it.
