Well that's news to me. I've never had it delete anything on its own before, and I've been using the infobox for over 5 years.

If it occurs again the next time you create a new page, let me know in more of a step-by-step description how you are adding the infobox. It could be possible that a strange error occurs if the infobox is added a certain way. You're probably doing it the same way we all do, but I just want to make sure you aren't accidentally doing something that would affect the code like that.
