Inc streamwise periodic gmsh

I have been working on replicating the Incompressible Streamwise tutorial case however I'm finding that generating a new mesh using the GMSH script makes the solver crash stating NPOIN is not the same as mesh file, even though I have made no change to the actual script.

in the su2 mesh file, check that you actually have the points, the connectivities and the markers present.
Then check that you you do not select 'save all point' when saving an su2 file.
Also make sure that you actually regenerate the mesh before saving, and that no errors have occured during the generation

Thank you. This is most peculiar. Regenerating the mesh in the GUI before exporting actually solved the issue.
