When exporting a terrain via the Micro exporter and Texture Coords are turned on, it looks like the UVs are projected along the mesh on the X axis, where it would be more useful to have them projected down on the mesh in Y.
I don't really use the UVs on an exported terrain as I mainly use the mesh as a guide (and turning off UVs on export reduces the file size), but I just wondered if I've missed something significant when exporting the mesh.
