Whilst setting up this bot the other day, I ran into a few issues:

• simplejson module is required, but not in the requirements.txt
• discord.py requires intents when setting up the bot

I was able to fix both of these and I can make a PR if you'd like.

If a user requests stats but they have not completed any parts the bot will throw an exception.
