Error when deleting a page with unsaved changes

hi bastian, first thanks for kirby to you and all the team. i have a registered copy of kirby. i get this error… (related to unsaved changes).

EDIT 1: i dont have theses pages anymore on content folder, i delete cache, sessions, etc.
EDIT 2: when i put that folders in content it works

That seems to happen if you delete a page while changes to that page haven’t been saved yet. I will create an issue.

Should be fixed now.
