Since I installed this addon, Steve's Carts has not been working properly. Some of the textures (such as the Engine and Chair) are completely missing textures and are now invisible. Marble also shows up as "Update TP" when held in my hand. When I looked at the texture file, I noticed it seems to be incomplete and had to revert to the default textures. Is this a WIP or am I doing something wrong?

So I've heard about the white GUI problem, but I'm having a very different issue. Whenever I try to create a "Chair" or "Engine", the item slot is completely empty even though the item is still there. I can also place the items, use them in recipes, and hold them... but they're invisible. I've tried multiple patches for Tekkit and Technic alike, any idea what's wrong?
