Thank you for reporting this error, we'll do our best to investigate the cause as soon as we can. Would you be able to tell us which version of Ren'Py you're using and what OS you're running on?
In the meantime, you can still open the source files in your code editor and use the code in there to assist you with your projects.
Sorry for catching your reply so late!
Ren'Py version: 8.0.3
OS: Windows 10 Home, 22HZ, build 19045.2251
Please don't worry about it unless it's going to give trouble for others!
(I personally ended up not needing to learn the layered image approach. I'm stronger in graphic processing than Ren'Py coding and my project size will likely end up pretty small)
And I have been looking at your codes! love how organized your files are, they have been great help taking preventative measures from code folder chaos.
