sethRichardson I replied to your PM, but will also add the info here.
I had a quick look at your file and noticed your "Noise_001" texture power is set to 0.100.
If you set this to 1.0 (10 times higher), then reduce your bump height by 10x (0.000010), the artifacts will go away.
For best results with the new bump height method, you need to leave your input textures at 1.0, then use the bump height pin to control the height instead.
Let me know if this works for you.
