I was exploring around the north eastern part of the map by some sewers, when suddenly as I crouched, my weapon and character turned invisible (kind of like chameleon camo) and the lighting got really bright and weird. At first I though Oh cool it must be me stealthing when i crouch or something but nope, turns out when I look invisible, I can't scope properly in first person and when I bring up my pip boy, it's either invisible as well with hard to read screen or invisible to the point I can't read it.
This only happens when I crouch (glitches for 5 seconds ish, returns to normal then glitches again numerous times). When I stand up its fine.
I've seen on YouTube other people have this problem. Any help? I've tried reloading saves and restarting ps4 and so on but nothing works.
