Sudden reboot problem in clover after changing region/language

Hey, guys!
After completing a successful high sierra installation with TB working perfectly, I changed the region and the language in the preferences and rebooted. When I got back to the bootloader there was suddenly a "happy new year" theme and when I press "boot macOS" the computer suddenly reboots.

I've attached the verbose print.

Does anyone have an idea of what's going on? Any help is greatly appreciated.

Thanks!
