the mod seems to work perfectly fine but its texture is of another item in my modpack (a stone spear from tiny progressions) and before that a block from libvulpes, another item was affected by this but i dunno why its happening with this, again it still functions and it has the clipboard texture when placed on the wall...

Can confirm this issue. In my modpack, it looks like the lemon launcher (item #6492).

Anyone have any ideas?

Can also confirm. In my modpack it simply displays as the magenta-black missing texture cube.

After uninstalling a completely unrelated mod, the texture has since gone back to normal. Seems that the missing texture was actually copied from a vertical slabs mod I used that caused lots of issues on its own.
