Mesh split plane / mesh trim failing - Grasshopper - McNeel Forum

Hi guys, I’m having some problems splitting a mesh I have of a TPMS gyroid surface. It was created using millipede and then offset a small distance (not sure if that matters). When trying to split the mesh in 2 with an intersecting plane something odd happens. It does not split the mesh into 2 seperate meshes 1 above and 1 below the plane. It splits the mesh as shown in the picture below. Any insight on why this is happening would be greatly appreciated! here is the file with in
