My in-game name was Nandeyo. I experienced the same issue both with Auto Progression enabled and disabled. I usually had the dialogue speed set to Fast. I would generally finish with more than 30 gold and around 2–3 unhappy customers. I played with the Master Volume turned down.
I’m not very knowledgeable about these things, and I obviously don’t know more about the game than you do, but after doing a little research, I’m wondering if the issue could be related to the game failing to load certain files/assets at that specific point. I couldn’t find any other issue that seemed to explain why this is happening on my end.
Thank you again for taking the time to look into this.
