I have created an error by accident I think. I had the site running on default English language.

Then I changed the develop site and took the language and changed it to swedish. This worked fine and I ran uSync to update the prod site.

uSync did not change the language, instead it added swedish and (as I remember) set it to default. Leaving english active as a second language.

I deleted english and everything was fine... I thought.

Until now. I have a node that is messing with me. If I try to unpublish it, I got an error (referencing a childnode). The node was unpublished, but I don't think anything else got unpublished.

So then I tried to delete it. It was removed. But now when I try to get all childs of parent node I get this

    Exception type: PanicException 
    Exception message: failed to get content with id=1391

   ...

I think that one of the nodes still is present with the en culture or something.

Anyone have any advice on how to tackle this?

Since I only have the error in the staging site, I can't really debug to much. I guess I can try to find something in the database and work from that?

Also notice now that the cpu usage on the server spike to 100% when entering umbraco backend. This started when I deleted the node. So I'm guessing umbraco is having a hard time generating the content-tree
