Arnold bake to texture using normal map creating artifacts

[paperthinportal]

My bake to texture render output is creating artifacts when a normal map is used. Software is Max 2022 with Arnold 4.3.4.12. I do not see anything strange in the normal map itself. Baking without a normal removes artifacts. There are no overlapping UV's or polygons in these areas. 

Things I've tried: 

• New default Arnold surface using only a normal
• Increasing ray counts using various combos of diffuse/specular/camera values
• Removing the environment map
• Trying various AA mode types (Gaussian, Mitchnell etc)

Well, found an odd fix. I scaled up the model 0.1% on the Y axis and that somehow reset some type of information in the mesh, now the artifacts don't show up.
