Problems adding and then removing events from the game map

[Phanixis]

Ok, I have been experimenting around with using RGSS to add and then later remove events from a map. I can do each operation individually without a problem. That is to say, if can remove any event from a map that was on the map when it was loaded, and I can add events to the map that weren't there when the map was loaded. The problem occurs if I want to use RGSS to remove an event that I created through RGSS as opposed to one that was loaded with the game map. When I attempt to remove an RGSS generated event, the corresponding event sprite is not removed from the game map.

Here is the code used to create an event:

def create_event(x,y,name="")

    # Create a new RPG::Event object (ev)

    ev = RPG::Event.new(x, y)    

    ev.id = $game_map.events.size + 1

    #print ev.id

    ev.pages = []

 

    # Create a game event object using map id and ev value 

    event =  Game_Event.new($game_map.map_id, ev)

    event.through = false

 

    # Set the event at ev.id to our event (include it in map)

    $game_map.events[ev.id] = event    

    #$event_instance[ev.id] = event

    #$game_map.map.events.keys.push(@summon_index)

    $game_map.map.events[ev.id] = ev

    #print $game_map.events

 

    # Map needs to be redrawn because a new event was added

    $game_map.need_refresh = true

    $scene.spriteset.add_additional_sprites

    event.character_name = name

 

end      

And here is the code I am using to remove an existing event

def delete_event(index)

    e = $game_map.events.delete(index)

    e.erase

end  

Does anyone know why using these scripts in conjunction cause a problem when they work fine when used independently?

Thanks for the help.
