Invalid avatar images
Some users who account is linked to a discord account have an avatar image which is pointing to an invalid image. This results in the text "User's avatar" which overlaps their username on the leader board. Here's an image:

It can be viewed simply by going to the overall leader board where there are three examples of the broken avatars.
I can take care of this one
Ok after a bit of digging, these are the callbacks that are called when a user logs in (using discord), in this order:
signIn callback
jwt
signIn event
Whenever a user does a full page navigation, the following gets called:
jwt
session
jwt
session
I assume 2 times because SSR + browser.
It does not seem like we have a lot of options for refreshing the user's Image, our session is 30 days, and unless the user does not open the website in 30 days, login will never be called.
At the same time, updating the user's image on every session would be too aggressive, we need to find a middleground.
