Moderator accidentally merged two threads - how to undo?

[LanaBoards]

Hi guys,

About an hour ago, one of my moderators on my forum accidentally merged two threads together, creating one mega 4400+ page thread. Is there any way to undo this mistake?? I haven't found a way to do so as a mistake like this has never occurred before, and it's creating quite a problem for our community as one of the threads merged is our most popular thread. 

Thanks so much.

There's no undo button, so from the interface, you'll need to select the threads that belong in one thread and split them off into a separate thread.

As Mr Cake says above, unfortunately there is no undo which means the arduous task of manually splitting.
