Deleting Container deletes all category-nodes... even transformed ones... with no warning

Hello,
Tried out the categorys module and it's pretty neat.

I used category_transform to change some flexinodes (w/ many fields) into categories. These were important pieces of content, since I am also using og.module (groups), and these flexinodes are also groups, so All my other content was associated with these flexinodes.

I decided to keep using groups to categorize this info, so I went to delete the container node, thinking it would remove the ability to select that containers/categories when posting/editing nodes.

When I deleted the container, without any warning except that I was deleting the container, it deleted all of my flexinodes that were set as categories underneath that container, important info, groups associated data, all gone.

My request is two-fold, and I think anyone in my situation would want the same:

If there is a way to transform nodes into categories, is there a way to turn them back into nodes without deleting all of them?
• Also, shouldn't there be some kind of warning that you are going to delete all those nodes?, since the ability exists to turn your content into categories?

thanks, and now back to repopulating my content!
