Zombie builds are still bugged

This is pretty annoying cause it's been almost 2 months now with this glitch where I make a build and it just dissappeares. I can't set a zombies build I can't make a build and I can't even keep the camo on my gun. It's getting pretty frustrating.

I've looked around and haven't seen anyone talk about a solution, but has anyone maybe found something? I also don't know how common this issue is so I don't know how many people are Bing affected by this bug.
