Hi, so i am playing FOV and iam stuck with the last clue cant find the 5th clue, where is it? Is it the runes that shine on wall? If that so where can i fin all the plugs i found 5 but it seems it isnt enough or its bugged or somewhere something opened but nothing is shown, help would be nice.

P.s. stuck with lack clue for 2h's now and i have done all the quests(well not the pull the trigers for runes to shine because i cant find all of em).
