So, what seems to have fixed it was checking the “Only Rim” box on the Solidify Modifier above it in the stack, but i am clueless as to whether it is a fix, or if it was not the optimal way to fix it, or even if i could go through this without needing a fix, and i am also lacking the understanding of why this happened… is it a Blender version thing, or something else?
Help is most certainly needed here to understand what has happened and why it has not worked by following along to this tutorial
