i bought the kiai sound , i used it for 2 days , then i sold it today .
some one bought it , i still get the sound tht i kept , in everymatch.
i saw my activated items its now even active.

Did that to me too. Its a glitch so you can pretty much buy a kiai sound or any sound for that matter, equip a sound to it and sell it and you should keep the sound. I'd say just use the glitch as a marketing trick. Pretty much a free sound.

This can be fixed by going into your custom folder and deleating the sound completely.(Not a bug/glitch, you still have the file inside your folder )People might still hear it, but tell them to re-download you again. You won't have any more prob after that, hopefully :v
