So, I have this part of the code from a quiz bot made with discord.js.
I set collector filter max: 1, but when 2 or more users reply with the correct answer in the same SECOND, they both get the points and it should be only one user, not 2 or more.

Example of this occurring:

The code:

const filter = (m) => !m.author.bot && m.content.toLowerCase() == current.answer.toLowerCase();
const collector = message.channel.createMessageCollector({ filter, max: 1, time: 45000 });

collector.on('collect', async m => {
    if (stop == true) return;
    if (m.content == null || current.answer == null || m.content.toLowerCase() != current.answer.toLowerCase()) return;

    collector.stop();

    remaining = Date.now() - time;
    points = remaining <= 5000 ? 10 : (remaining <= 15000 ? 8 : remaining <= 25000 ? 6 :(remaining < 35000 ? 4 : 2));

    message.channel.send(`Correct! The answer is **${current.answer}**\n**${m.author.tag}**! You got **${points}** points!`).catch((err) => {console.log(err)});
                        
    if (fs.existsSync(`./system/users/${m.author.id}.json`)) {
        data = JSON.parse(fs.readFileSync(`./system/users/${m.author.id}.json`));
        data.total += points;
        data.current += points;
        data.tag = m.author.tag;
        fs.writeFileSync(`./system/users/${m.author.id}.json`, JSON.stringify(data, null, 4));
    } else {
        fs.writeFileSync(`./system/users/${m.author.id}.json`, JSON.stringify({
            "id": m.author.id,
            "tag": m.author.tag,
            "current": points,
            "total": points
        }, null, 4));
    }
    await wait(5000);
    return(md('NEXT'));
});
