as a sorcerer, when casting illusion gate or homeward bound skills, for some reason there's a sound glitch at the end of skill cast for it is not properly completed or heard same as for the wings toggle up and down, tried to force recheck game, deleted bin folders, game (.cfgs) files and reinstalled sound driver but problem is not fixed. any help would be appreciated. 

Hello,

Do you have problem on some exact skills only? Or generally with all the effects?
