Everything gets displayed properly even when adding multiple children all over the place, but as soon as another root node gets in, it gets wonky. Only happens in Admin. Likely has something to do with TreeAdmin's get_ordering method, but I'm curious if you're able to re-create this with your Page model.\n","author":{"url":"https://github.com/kronok","@type":"Person","name":"kronok"},"datePublished":"2016-09-23T19:23:20.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/2/feincms3/issues/2"}
