Yes I am sure they will have a fix. As it is now you would have to figure out who you have deleted and either delete the posts from that old user or create a user of the same name.
With UBB5 series it would just mark those users as unregistered. I would think a simple bit of code that would say IF member profile = null them member number = unregistered.
Looks like this will be going to bugs...Glad I didn't upgrade my other UBB ! Man I would have been in a world of hurt. I feel for ya Ryan.
Until they come out with a fix try identifing the deleted uses and recreate them. This way at least you won't have to delete posts.
Best of luck...
