The only way to stop this is for Microsoft to release a patch on the console itself. It's not a problem with PUBG, it's the console that allows it. And why would Microsoft stop people using mouse and keyboard, when they have thier hands in PC gaming too? The Xbox One is basically running a stripped down Windows 10 anyway, the Xbox one is more like a PC then it is a console. That's why it's so easy for microsoft to have all thier latest games run with Xbox One and Windows 10. So you see, you shouldn't be posting on the PUBG forums about this, you should be posting on the official Xbox one forums. BlueHole cannot do anything about the keyboard and mouse issue.
