I have been having a recent issue with the Pipboy interface that I cannot figure out. Randomly when going into Pipboy mode the background screen behind the Pipboy is completely black. Normally when enabling the Pipboy the background imagery is that of whatever are you are in, but here and there the entire bakground it black. Anyone have any idea why this might be happening?
