I have been playing Fallout 4 for two weeks and really enjoy it. However, after going into the HalluciGEN building I have a repeating 'flash' of lighting that occasionally makes it look like I'm using a Stealthboy (I'm not) and renders the pip boy screen either faded out or completely blank. I've re-loaded a previous save and actually erased a few saves and started from a couple hours earlier than getting to the HalluciGEN building. Still have issues with the flashing every couple of seconds and stealth/pip boy issue. It isn't game breaking but it does ruin the immersion and enjoyment of the game. Is there a fix coming and has anyone else encountered this? Are all my save files stuck with this now??
