I have one button on my mouse configured as a back button. I sometimes manage to fat-finger it with my thumb and it closes the open map (such as daily challenge). After re-entering the round, my guess location is lost.

Please store the guess location for the active round in the browser so that it restores the guess location when I re-open the game after such messup.

For example today I knew I selected a location before this happenned and the game didn't really tell me that I had no location set because of the re-enter.
