My entire configuration reset entirely upon downloading the latest version today, this happened a few times before. I have quite heavily modified all my settings to fit my preference, including mouse sensitivity, font scale, attack control, music, key configuration, optimized graphics settings and so on. It is quite a nuisance having to redo it. Having to find or remember all my old settings. I dunno why this happens, but if there is a way to prevent it, please do or please tell me.
