Hi, This happened to me too, but fortunately I figured out what it was. In my case it was because I missed to config the Install Order on some apps, be sure to set these numbers one by one and not repeat or miss any of them, if you have 10 apps you got to have 10 order numbers from 1 to 10 Tip: Use WPI Config Lister to view the ordered list of apps you have in your config.js file. Hope I could help you.
