  found_events = Array(list).flatten.compact.map {|s| events_for_target(s) }.flatten.compact
  found_events

#reset! ⇒ Object

When the game is reset the event dictionary needs to flush out all of the events that it has loaded as the game files will be reloaded. All metro related components will not be removed as those files are not reloaded when the game is reloaded.
