So, my wife and I are working on a texture pack together, so far everything else in our texture pack seems to be working...except for the grass block top. We've put our own texture in, at x256 resolution, but when we enter Minecraft itself, it remains the default grass. We're working with an absolutely FRESH installation of 1.14.3 and the textures are multiples of 8, not a pixel off. There is also no CTM data that I'm aware of, so it isn't that. Is there a reason why it would stop working?
