Any updates on the bug when AI suggest new code identical to the current?

These happens overwhelmingly often. Needless to say there no value when AI works like this:

"To fix this issue, we need to ensure that theoryParts is properly imported and initialized before it’s used in the ui.js file. Let’s modify the ui.js file to import theoryParts from main.js.

First, let’s update the import statement in ui.js:
import { adjustLayout, adjustScrollableAreaHeight } from ‘./utils.js’;
import { setCurrentTheoryPart, theoryParts, getCurrentTheoryPart, getCurrentLanguage, setCurrentLanguage } from ‘./main.js’;
import { presentTheoryPart, endSession } from ‘./session.js’;
import { translateUI } from ‘./translation.js’;

Replace these lines with:
import { adjustLayout, adjustScrollableAreaHeight } from ‘./utils.js’;
import { setCurrentTheoryPart, theoryParts, getCurrentTheoryPart, getCurrentLanguage, setCurrentLanguage } from ‘./main.js’;
import { presentTheoryPart, endSession } from ‘./session.js’;
import { translateUI } from ‘./translation.js’;

Now, let’s update the showNextButton function in ui.js:
export function showNextButton() {
const fixedBottomArea = document.getElementById(‘fixed-bottom-area’);
const nextButtonArea = document.getElementById(‘next-button-area’) || document.createElement(‘div’);
nextButtonArea.id = ‘next-button-area’;
nextButtonArea.innerHTML = ‘’;

const nextButton = document.createElement('button');
nextButton.textContent = 'Next';
nextButton.classList.add('next-button');
nextButton.onclick = async () => {
    nextButton.disabled = true;
    const currentPart = getCurrentTheoryPart();
    const nextPart = currentPart + 1;
    if (nextPart < theoryParts.length) {
        setCurrentTheoryPart(nextPart);
        const subject = document.getElementById('subject');
        const grade = document.getElementById('grade');
        const theme = document.getElementById('main-title');
        
        if (!subject || !grade || !theme) {
            console.error('Required elements not found:', { subject, grade, theme });
            nextButton.disabled = false;
            return;
        }
        
        await presentTheoryPart(subject.value, theme.textContent, grade.value);
        nextButton.disabled = false;
    } else {
        showEndSessionButton(nextButtonArea);
    }
};
nextButtonArea.appendChild(nextButton);

if (fixedBottomArea && fixedBottomArea.parentNode) {
    fixedBottomArea.parentNode.insertBefore(nextButtonArea, fixedBottomArea);
} else {
    console.warn('Fixed bottom area not found');
    document.body.appendChild(nextButtonArea);
}

}

Replace this entire function with the following code:
export function showNextButton() {
const fixedBottomArea = document.getElementById(‘fixed-bottom-area’);
const nextButtonArea = document.getElementById(‘next-button-area’) || document.createElement(‘div’);
nextButtonArea.id = ‘next-button-area’;
nextButtonArea.innerHTML = ‘’;

const nextButton = document.createElement('button');
nextButton.textContent = 'Next';
nextButton.classList.add('next-button');
nextButton.onclick = async () => {
    nextButton.disabled = true;
    const currentPart = getCurrentTheoryPart();
    const nextPart = currentPart + 1;
    if (nextPart < theoryParts.length) {
        setCurrentTheoryPart(nextPart);
        const subject = document.getElementById('subject');
        const grade = document.getElementById('grade');
        const theme = document.getElementById('main-title');
        
        if (!subject || !grade || !theme) {
            console.error('Required elements not found:', { subject, grade, theme });
            nextButton.disabled = false;
            return;
        }
        
        await presentTheoryPart(subject.value, theme.textContent, grade.value);
        nextButton.disabled = false;
    } else {
        showEndSessionButton(nextButtonArea);
    }
};
nextButtonArea.appendChild(nextButton);

if (fixedBottomArea && fixedBottomArea.parentNode) {
    fixedBottomArea.parentNode.insertBefore(nextButtonArea, fixedBottomArea);
} else {
    console.warn('Fixed bottom area not found');
    document.body.appendChild(nextButtonArea);
}

}

These changes should resolve the ReferenceError by properly importing theoryParts from main.js and using it in the showNextButton function. Make sure that theoryParts is correctly exported in main.js as well.
