Forum Posts shifting when 'Unapproved'
 

I've just noticed an odd error in our forums.

I unapproved a post and once I did the post below it shifted up and replace the unapproved post, but under the unapproved post author.

So the post below, suddenly belonged to the author above it.

Any ideas? I realise I can delete/move posts, but just wondering if theres an easy fix to this unapprove issue.
