1. This is the wrong way to post a log. Attach it.
2. Have you even tried locating the problem file? We are not here to do your work for you. Start with anything dealing with witches, effects, and custom skins.
Oh yea, I haven't checked the custom skins... Almost forgot even if you've disabled CC in games, custom skins, walls, floors, terrains will still affect the game... Thx for the reminder.
UPDATE: Okay, now I'm pretty sure it's due to something from my Downloads folder. The problem's gone when I've completely removed everything from "Downloads". BTW, is there a way I can track down on which download has caused such a problem
