Mc: 1.17.1
Fabric Api: 0.41.0
Mi: 0.6.0
Rei: 6.0.279
architectury: 2.6.35
Texture pack: Bleached-Fabric-v1-2_Custom.zip

Steps to reproduce

1. Open minecraft with provided Texture pack enbled
2. Open pretty much any Ui from the mod

Note: screenshoots are taken with nothing but mods above, so Sodium is ruled out & I doubled check that everything is textured properly and it is

Also a semi unrelated note a texture in "textures/gui/progress_bar/furnace.png" isn't a proper png, looking through a hex editor indcates it's an "BM–" or bmp with .png extenstion

Finally fixed this, sorry about the delay!
