I'll have to disgree, Cari. Here is my reasoning.

Mount Justice is still devastated after Impulse left - but now we know why. Animation's not the same as live action - everything you see was put there purposely. Therefore, it's highly unlikely that the lack of ash is a goof - why would they animate falling ash, and then re-animate it without ash the second time around? It would be cheaper to re-use the earlier footage, right?

Besides, "nothing's changed" came from the mouth of Neutron - someone who was standing too close to the time machine, and whose memories of the old timeline still remained. He could only base his conclusion on what he immediately saw - his change of costume, and his lack of scars and power inhibitor collar. To his viewpoint, the devastated Mount Justice means that nothing has changed - he didn't notice the lack of ash either.

Here's a before and after comparison:

Mount Justice looks the same, but there's no black snow. It's hard to tell, and I'm not going to insist on it. But it looks like Happy Harbor is less devastated in the after pic than it looks like (it's heavily obscured by the location text) in the before pic.
