Cannot delete this collection as it is used in bindings

[samliew (webflowexpert.com)]

I managed to track down how users can end up with a state where a collection is unable to be deleted as it is used in bindings.

Steps to repro:

1. Create collection
2. Add normal page
3. Add collection list to page
4. Add elements in the collection list. Bind to fields in the collection
5. (optional?) Publish and unpublish site
6. Delete normal page without deleting collection list first
7. Now when you delete the collection, you need to request @staff for a “hard-refresh” on your site, or rollback to a previous save state before the collection was created.
