I'm a big fan of sound modding, and I've edited many of the game sounds (music, user interface, hero skill sounds, and announcers) through the script files. However, changing the file game_sounds_items.txt seems to have no effect. Specifically, changing the sound file pointer

"wave" ")items/....wav"

doesn't have any effect on the game, unlike doing the same thing for skill sounds, announcers and music. Can anyone shed some light on this?
