Like the rest of us no clue about any changes.
But the refining interior annoys me, well one bit of it anyway. There is a rolling mill and you can watch the metal entering going under the first roller and being transformed then the subsequent rollers change its shape even more the problem is all the rollers are going the same speed but the first roller squashes the metal down so it is thinner but there is still as much metal so it has to speed up, the end roller should be going much faster than the first one to be right, it also looks better.
