That's actually quite common to be honest at least from my time there. Just refresh the new page a lot and will see quite a bit suddenly disappear after a refresh. Sometimes lasted 4 refreshes at most, but still disappeared. That is the main sub though, and the fact that most of the time it keeps being UPI, solar is king, all hail green, and such when not dealing with biology(it has been a while though so do not know if it has changed).
