Convex mesh collider thinks model is non manifold but it isn't

Questions & Answers

I’m getting this error in unity on my convex mesh collider.

Adjacencies::CreateDatabase: can’t work on non-manifold meshes. Try to use the PxConvexFlag::eINFLATE_CONVEX flag (see PxToolkit::createConvexMeshSafe)
UnityEditor.DockArea:OnGUI()
GU::ConvexMesh::loadConvexHull: convex hull init failed! Try to use the PxConvexFlag::eINFLATE_CONVEX flag. (see PxTooklit::createConvexMeshSafe)
UnityEditor.DockArea:OnGUI()

The thing is my mesh isn’t non manifold. It has less than 255 triangles. I’ve used blender’s Select non-manifold and it comes up with nothing. I’ve tried deleting doubles but there aren’t any. I have no idea what’s wrong. I have another mesh that is very similar and when I use it as a mesh collider I have no problems. The mesh is a .blend file. Here is an image of the mesh:

I fixed this by getting rid of half of the edge loops since I didn’t really need them. Don’t know why that fixed it but it worked.
