Ahem, that guy is me
And yes, that's exactly the name for the pack I made, but a little correction first:
"created some presets to replace a lot of the neph in the game"
The pack replaces ALL neph presets in the game that aren't slender by default (i.e. everything that is ≥slightly "chubby")(so all except Foxen, Harpies, Bats, Vulwargs and a few Hybrids).
The most recent pack is here:

It's not updated for the version released a few days ago, but if I recall correctly all Dere implemented was the Fern update and the pack should still work properly.
Also, I have no clue, how to change the general preset values for the auto-generator of Nephelym, or else I would make a general plugin, that changes the default values for every fat neph to be slim.
