Sometimes promoters tweet more than once.
Tweets will only get updated when you re-fetch them. This helps you because competitions will no longer "jump" between pages when competitions get added or competitions finish while you are browsing them. Competitions get "fetched" when you login or manually re-fetch them with "Forget Ended Competitions & Fetch New Ones". Additionally hidden tweets will stay visible until you "fetch" to save reloading the page and save you from losing your position.
