When I view the Quark configuration menu, both the checkmark and X don't appear. The stranger thing about this is that a piece of the check or X appears underneath the slab rotation lock for the top and bottom respectively. I've added three screenshots that show each problem along with the latest.log:

• Are you using any texture packs? If so, try disabling them.
• If not, please cause a forced game crash (hold F3+C for 10 seconds) and send that log.

I'm not using any resource packs and I've already tried reordering the mod resources and default as well as reloading the textures. Another observation I've made while looking in the resource pack menu is that there seems to be a ghost pack that can be reordered between the default and mod default.

Weird.
Can you reproduce this without any other mods but Quark? There's a chance someone is accidentally shipping an old version of the texture.

During my tests, I've only been using Quark and the Oddities addon, yet this still occurs. I've also tested it in the latest release and the glitch is still present.

Can you send a copy of your mod zips?
