[quote name='Tavohl']i killed the last boss on world 5, maiden astrea, so i got pure white world tendency and decided to go look for BP garl vinland, and he was there.... but i was about to kill him, and he healed himslef, wich pissed me off, so i quit the game and thought about returning later. and when i loaded the game again he wasnt there and the world tendency wasnt pure white anymore.... any one knows what might have caused it?[/QUOTE]
If you were signed into PSN when you reloaded the game your world tendency is averaged between the server (which is an average of all the rest of the player's world tendencies) and your own world tendency. Since the server tendency is never pure white except during special events, your own world tendency will always shift down to just below pure white whenever you load a character while logged into PSN.
If you logged out of PSN before starting up Demon's Souls, then I don't know what happened.
