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.
