Agreed, but I don't know why it's so finicky. It doesn't happen at specific points along the questline (or maybe it does?) and even if did, it definitely doesn't happen with any significant consistency. I'm sure there's some silly code/mechanic where there's crossed wires somewhere as I've seen enough reports of it to indicate it's more than just a random occurrence that happens once in a blue moon.
I have the exact sane problem but im goin to see if that relitives highlighting thing works thanks!
