Banners Banned Me????

When I first entered my single player world in snapshots 14w30a, b and c; I noticed that when i attempted to get the banner item (every way possible) my game crashed and said... Registering texture as the description. I attempted this 10 times and had the same result every time. Crashing my game. I have uploaded many complaints and i hope , since this is more formal, my issue will be resolved once and for all so i can make kits 85 and 86 for my future 1.8 multiplayer server. I hope you (as the public) can comment some suggestions to help resolve my problem. Sencearily. Jack. 🙂
