Oh nooo I'm so sorry that happened!
I've just pushed up a few fixes that make it really (really) explicit what will happen - and it no longer morphs your active pet at the end of the process, but lets you choose a pet and shows you what the change will be.
And the guide is more clear as well 🌱, one of my goals with all of the changes on Subeta has been to be able to more easily explain things on the site, thank you for calling this out!
