3D Print of Dune Knight

Which version is thowing the error? Supported or Unsupported? Someone else told me this is happening but I haven't been able to reproduce the error having tried it with Meshmixer, Lychee, orca and of course: Zbrush. I think I'll give it a go with another software before I jump to re-exporting but Would like to know if both versions are behaving weird.

Here's my printed one.
