Steps:
Detailed steps on how the issue occurred.
I bought from the market board and used the "Now I Know the Truth", but got the "Out of the Labyrinth" music instead of the "Now I Know the Truth" music in my Orchestrion Log.
I already reported the opposite bug ("Out of the Labyrinth" orchestrion roll gives the "Now I know the Truth" music when used) so I think it's just a miss-nameing.
