would love a full list of these if you have it! I'm a self taught programmer, so i tend to make a ton of silly errors.
I've forgotten most of the changes I made, but I do have a copy of my files with all of the errors I could track down fixed (making every portrait unlockable, except for one I had huge trouble with), and with that transformation you mentioned earlier removed from all of the game files except for the one for the update it was introduced in (so you could delete that if you'd like, or keep it around if not), and its forms removed from the list in the gallery
If you would want that, let me know!
