Afraid of the Dark Bug

PS4

Version 2.18

Still have the afraid of the dark bug to this day :(

It's annoying! I do not use cheats, and already tried the potion, the turn-off want and fear. Nothing works. 

We can't even use mod to fix this looooong on-going bug. Why is it so hard to fix, though? It has been literal YEARS at this point.
