Yup, noticed that... This method is parsing the title after it's inserted into the database, while uShop is parsing the title before it's inserted into the database, which could create a problem if you still wanted to allow some users to use HTML. I was working on this for a client and noticed the post caching problem, came here to search real quick and see if anyone had posted about it (and found this post obviously), and decided to post the fix after I figured it out incase it would help anyone else.
