idk if this is the proper place to put this, but the answers to the conversation with Barcus in Last light about Wulbren doesn't make sense.

I've already agreed to look for Wulbren after the Grymforge, I already know how the gnomes got trapped, and I already know who Wulbren is to Barcus... why are all the options implying I never agreed to it? It just doesn't make sense.
