Why the hell is that sometimes when i tweet a @YouTube link the tweet has a preview and other times it doesn't?

So long as the thumbnail is updated before you publish and send out the notification, we believe Twitter should use the correct one! It looks like they only craw/re-index once a week, so that's why it could be delayed if you update the thumbnail post-publishing.
