Why I run in editor well but build project cannot run leapmotion? about unrealplugin HOT 1 CLOSED

WTF!!!!!!!!!!!
I know the issue，when I Drag and drop Plugins into your project root folder，and I restart project and check the plugin true，but the fucking UE4Engine remove the leapmotionplugin config of xxx.uproject file，

so the right way is :
after copy the plugin folder and restart your project , you must check the plugin false in editor， then close project and right click the xxx.uproject and edit it in NOTEPAD

"Plugins": [
	{
		"Name": "LeapMotion",
		"Enabled": true
	}
]

then start fucking again UE4project , then build it ,run it ,DONE!
