Clicking "Delete World" right after dying in Hardcore Mode doesn't delete that world.

What I expected to happen was...:
The world would be deleted automatically.

What actually happened was...:
The world never deleted, and had to be deleted manually.

Steps to Reproduce:
1. Create a Hardcore Mode world.
2. Die in that world.
3. Click on "Delete World"
4. You will be brought to the title screen. Go to the world selection and check if that world has been deleted.
