I just had an encounter with "darkness" and saw that mafia didn't identify that an inkwell was needed, or that I already had one in inventory. A clannie also reports the same problem with "Fickle Finger of F8". I guess we both relied on mafia a bit too much, because we both went backfarming without checking inventory ... 
Anyway, I guess this was caused by r11622 and can be fixed by updating GUARDIAN_DATA in net/sourceforge/kolmafia/session/SorceressLairManager.java.
