Can't turn in Eyeless Quest - Helm

I finished the Eyeless quest, killed the beholder, returned the rift device to the diseased ones, and went back to the temple of helm to claim the reward. However, Oisig just says his standard "may helm watch over you..." message. My last journal entry still says I need to return the rift device (which I already did) and then go back to the temple. Is there some variable I can edit in EEKEEPER to make the game give me credit for destroying the Rift Device?

First, the BeholderPlot global variable to get the right conversation; this is set to 1 in the dialogue when you accept the quest. There are also WorkingFor___ variables to indicate which church you accepted the quest from, but they're not checked in the key dialogue.
Second, for the response that completes the quest and earns your reward - is the Unseeing Eye dead? It doesn't matter how you killed it, only that it's dead.
