Honestly, I am just going to hit the reset button xD, so many different things are wrong with the scripts and animations to count. It would be faster to start from a fresh install of Rpg Maker MZ with minimal plugins.
Oh, you don't need to reinstall MZ, just make a new project :D Good luck with it :)
Feel free to join another one of these jams, hopefully it will go better this time. :)
