Deleted collections still on collections page.

I've got a problem with my collections page.

I went and deleted some of my collections, however they still appear on my collections page. However when you click them, it does just lead to an error page.

I would like to have these collections actually deleted from my collections page so that they're not just taking up empty space.

Thanks

Reorganized mine and ran into the same problem, they disappeared when I created a new one, though.

Sounds like a caching issue, I'll bring this to the attention of @kisuka
