I've made and uploaded a custom texture pack to my server via garbageloan, and even though I've removed the files from the subfolder they were in (because I found out the hard way that the site doesn't acknowledge anything not in the root of my .zip folder), I'm still not seeing my textures for the hotbar. However, as expected, terrain.png works and has for the whole time I've had this texture pack.

Is there something I'm doing incorrectly where the gui.png would be working properly but isn't?

Does flipping the Classic GUI textures option in Nostalgia Options make it show up? If that doesn't help, maybe garbage.loan is still deleting it?

Sure enough, didn't even realize I never turned that off. Thanks! Also helped me realize that the dimensions of the classic GUI aren't the same as vanilla. Seems the website's deleting gui_classic though.
