Issue: Headline does not work in Forum posts

Our regular forums have a time limit of 30 minutes for editing posts.

I recently installed the automatic thread merge hack and was trying to get my users to use headlines when they wanted to divide content in a post.

Once the edit period has expired the links on the headline are "broken."

Collapse and Top are silent as I might expect. Edit goes to a non-existent page which my board traps and directs to a friendly post.

If there were a way to make the headline not show the links in normal posts, that would be a sufficient solution for our purposes. Alternatively, we can just leave headline off the normal post menu.
