Bad reference to parent site

Hi everybody,

I have unfortunately not found any topic related to this issue, so let me explain what's wrong:

I created a template from an existing site, and used it to move it to another parent site (bad). My main mistake was to delete the template afterwards... (very bad) Indeed, I lost all site columns and file types I had created. This could be easily recreated fortunately.

However, I have also noticed my susbsite's reference to its parent site had not changed. When I check Sharepoint 2010 breadcrumb, it still shows the old/wrong parent site. In the same way, clicking "Go to top level settings" in site settings drives me directly to the top-site instead of the new "Library" parent-site.

Curiously, every single new site I create under "Library" inherits from the same behaviour. I have tried to find the parent site reference directly in the database, without success.

Does anybody have a clue about how I could fix my bad prent-site references?

Thanks a lot in advance.
