- When walking into a Guild Dungeon your pvp_points will be set to 5 so you have to die twice before being warped out.
- If jobchanging while disguised, the disguise will be removed, since it can't be kept and still calculate correctly the new job class to use.
- Fuuma shurikens are now unbreakable code-wise (like all maces, books, etc)
- Applied Meruru's patch to increase speed of easy path seeks.
