XF 1.2 Moving posts/ merging thread

[Morgain]

I've lost track of how to do this. On the older versions I could do it but on my 1.2 when I select a post to Move it, all I can do is select a forum to move it to.
It's already in the right forum but is an unnecessary thread so I want to move it on to an existing thread.

You need to select two threads first, then choose merge.
