I cannot access the secret room in "Endless Paths of Od Nua Level 5" which contains the Blade of the Endless Paths. I know the adjoining room has a hidden switch, but no matter what I do the switch remains hidden. I am in stealth mode, I have two characters with 16 perception and I am standing right next to where the switch should be but it never appears. Any help would be appreciated
