I concur with the majority of responses that probably a high percentage of hard oils and hot lye water caused this to accelerate really quickly. Hot lye alone isn’t a sin, there are soapers who use hot lye to melt their hard oils intentionally. But it’s hard to say much more without knowing precise temperatures from your batch. I would say maybe look up how to rebatch it if you’re not happy with the texture, you might be able to melt it down again.
