I'm pretty sure this happened on 1.8 and is still a thing on 2.0 but I find it incredibly annoying that if a user's login session token expires, rather than flarum forcing a page refresh, it'll just throw errors forever until you manually force a refresh yourself.
The worst part of all is that the error isn't very indicative and you'll see it when casually browing a discussion without even trying to do an "action" that requires you to be logged in.
