Changing model makes generation returning the same result over and over again
Generated an image with model Gemini 3.1 (Nano Banana 2) and used the same prompt and reference image with Gemini 2 (Nano banana pro): it gives me the exact same image (same name starting with "Firefly_Gemini Flash" and ending with the same number "235558". Something is not working and I hope I'm not debited of 40 credits to be served with the same result
