Hardcore mode restraints (Cheats, Bonus Chest) look as if you can modify them, but you cannot modify them. This happens after selecting hardcore mode, setting terrain generation to customized, clicking the customized button, and returning back to the Create World menu.

What I Expected:
The hardcore mode restraints should be shown as a darkened non-intractable button.

What Happened:
The buttons were highlighted when moused over, and looked intractable, however they couldn't be modified (could not enable cheats or bonus chest)

Steps to reproduce:
1. Create new world from the world menu
2. Set to hardcore mode
3. Set terrain generation to custom
4. Click the customize button
5. Exit out of the customization menu
6. The buttons are highlightable
