Probably better to have that chat here instead of CHAT. 
Get on that and try with Google Gemini 2.0. You can download the folder you’ve been working on and should be able to restart OK.
I make a habit of storing my prompts in a doc and if I have to roll-back or use them in future I can. That way starting over is quite easy and efficient. If I find prompts are leaing the wrong way and getting a bad result, I modify them, roll-bcak and try again.
Gemini 2.0 is free so experiment to your hearts content.
Let us know how you go.
