Ok. i tested other sound object. because on one i got complain sound volume cannot be changed from userdate.
Well, it works fine. I only forgot to add the text that the user need to reload the script. Nothing broken.
But now i cannot correct this on the other items. So i guess at some point the get removed because something silly like this. If the get removed, do not expect the get replaced soon. i cannot access the old data to. when that happpens.
