Patch 8 (technically 9) is live on Origin. Here's hoping that it doesn't break modding 
It breaks both mods and the Mod Manager. *sigh* Someone needs to see if incrementing the package.mft in the modded folder fixes at least the mods being broken. I can't do it for several hours, unfortunately, or I'd do it myself.
UPDATE: Someone on the DAI Tools forum said that incrementing the package.mft file on an existing Patch folder fixed the problem of mods not working. But Mod Manager can't merge mods with Patch 8 anymore (not surprisingly).

but Adela and I have been trying different things, and it's the mesh import things that are the trouble, so we have come to the conclusion that it's not the exporting of my hair mod that is the problem, but the tool itself
Oh, how frustrating! I hope a solution is found, I like what your first version looked like a lot!
