Looks like more "joys of open source". Threads with special characters (quote marks, ampersands) in titles are doing interesting things in the forum display. For instance, this thread looks fine when you actually open the thread, but in the forum display the quotes in the title are displayed as """

I don't remember this being a normal issue, I could be wrong.

this happened to me a while back. i just went back and changed my title.

It seems to happen to the titles of threads that get reposts or other threads merged in. I do what RickySlicky does and edit them.
