Hopefully fixed for the next release.
The way the species override setting worked was being overridden by the centaur naming function, so it should now skip that if the override name already matches with the calculated name prior. However if this change messes up any other name override configurations, it may need to be tweaked further. This should notably affect taur, drider, naga, and MLP races, as well other hybrids, I think.
And on the automated end, I adjusted the taur naming to allow horse-legged, human-faced, "pegasus", "unicorn" and "alicorn" to show up as "half"-taur races, with "centaur" being a fallback for those that do not otherwise fit the prerequisites. I also slightly adjusted the weighting between "pegasus", "unicorn" and "alicorn" to get the auto-generation to be a bit more accurate. But again, it may require tweaking if it conflicts with anything else.
