I've said this before and even made a thread about it. Before you update your client replace the lang0.pak with an unedited one. So before you ever English patch copy the pak and save it in your documents or where ever else you want to put that thing and when you know that you will need to update the game switch your patched lang0.pak with the original. All issues solved forever more. You get the minor translation that you don't really need to play the game and no need for reinstalling the entire client.
