Every function created is created as an episerver page in the [Extension Data Container] node. However they never seem to be deleted! I tried creating a function on a page and then deleting it, I also deleted all the version of the page. However the function page still remains.

I don't want to think about how many pages this will accumulate over time, bogging down the system.

However a more serious short term problem of this is that we have images from imagevault that's been used in functions that's been deleted. And now those images can't be deleted since they are being used on a page that shouldn't exist.

Is this by design, or a known bug?
