I've been trying to complete the quest that allows me to get to Evelyn. It's the one where there are two underground dungeons and you have to light the elemental columns in each dungeon to gain access to the area where Evelyn is. I activated all the columns in one of the dungeons by using the information on the sign in the other dungeon. When the NPC spawned I killed him and the trap door appeared. However when did the same thing to generate the spawn in the other dungeon, the columns will not light. I've tried every possible combination in addition to the one that's supposed to work with no success.
Is this a bug or am I doing something wrong? Any help would be appreciated.
