fix(gs/xanthous): Check for reaching destination in AI r/3077
Because floating points, it's possible that a creature has reached their
destination even if the *progress* to that destination is at 0 - if that
happens, they should pick a new destination regardless. This fixes the
issue where creatures would occasionally get "stuck" and never move
after wandering around for a bit.
