Getting the exact same thing. Harry confessed, ran straight to Stanley to tell him. Unable to find the right magical combo of words to proceed or end the quest. Constant "A tragedy, that. Those refugees have seen enough pain already. Please, if you find out who is responsible do let me know." Except I kept stating that Harry set up / lit / started / confessed the fire etc. etc. Plus, the journal says "I can tell Stanley, Martin's superior officer,". Stanley is the boss of a merchant? So I tried to use both Stanley and Martin. Will not proceed.
