OK but the Vision in the Hex is actually real. He's made of Vibranium that can be detected from the outside.
And it's shown that things that make it out stay transformed.
So she literally remade the Mind Stone then if he has all his powers.
Yeah, my take on it is that Wanda is essentially manipulating the physical form of things to either make them as they were decades prior to present day or turning them into objects that would fit the time period inside the hex.
However, since Vision was actually recreated inside of the Hex and not just brought in, he can only exist within it. That's why his body was getting pulled back in piece by piece.
