Okay, so I've installed the CK, launched it, loaded Skyrim.esm. Then I tried to make a very simple plugin. Duplicated a cell, renamed it, selected all the objects in it, pressed Delete, answered Yes, and... nothing. Okay. I've tried that 10 more times... nothing. Okay. I've tried to remove the created cell and... all the objects it contains disappeared, but not the cell. I went to the forums just to check if someone else posted such an issue, then I restored CK window, and get message "This program has stopped working". Okay. I've relaunched CK, opened my plugin, tried to delete the cell and... again... nothing. Why the Universe is so unfair?~

Deleted cells and worldspaces stay there with the *D tag until the next editor reload.

However bear in mind you can't delete anything from Skyrim.esm. So if you made a cell and delete that, fine. But you can't delete vanilla forms or BadThings^TM will happen.

Okay. But why the OBJECTS are not deleted until I delete the cell? =___=
