The Farmer's Frenzy fight causes the screen to go black and the picking a fight selection pops up again but if you close out of the selection (pick nevermind) the fight starts and the first two fights are normal with the bandits and the bandit leader but the final with the lady whose name starts as a B doesn't work properly as the prefight dialog is right but the fight itself isn't with her and is instead the Unholy's memory fight. The rewards work tho.
If you're talking about right after "The Monolouge", Kadone tells you the following (if you read it wink wink)

And to you, Julina, I have an offer to my closest of friends.
You may play in my magical games where fun never ends!
To have fun, go to where we fought and then enter the cave.
There is no funny business there though so you best behave!
