Universal Rules are accessible during startup slave customization, but there's no button to confirm/go back, so you're stuck there

Steps to reproduce:

1. Go to Body Mods tab and brand a slave with "your initials",
2. Now under "Branding" you'll have a standard message of, for example, "Her left buttock is marked with your initials, your official brand: Remove Brand",
3. "official brand", however, is a hyperlink that opens Universal Rules,
4. If you clicked it, now you're stuck, since there's no way to get out of Universal Rules here.
