Howdy! I'm glad you enjoyed it!
The 11th slide is in fact a bug, not your fault. What's happening is that I have an image in my Author's Notes, and the compiler I'm using is bundling it as a Base64 image, but the StoryFormat I'm using is showing that image as text in a separate passage.
In other words, I just had a skill issue in compiling the story ;)
I'll update in a few minutes.
Updated! Both issues have been fixed. Thanks for helping to make my story even better!
