I cant get it to work, the problem is:
- When it teleports me out after i kill the dragon, the dragon its not set as dead (game.set_event_flag("dragon_lair_alive", 0).
When i click again on npc it dosent give me the message "dragon is dead you cant enter..." it gives me the option to enter again in the dungeon....
