Worldguard - Cannot Die w/ __Global__ build:deny

It is NOT my configuration, and I know this for a FACT. After reinstalling worldguard and several plugins, I've narrowed it down to the way I protect my spawn world.

Anytime I add an owner to use the build:deny flag on __Global__ players cannot die, no matter what, no matter the permissions.

I have a world_spawn and it houses minigames and floating islands where you need to be able to die?

Invinicibility is not enabled, and I've tried adding the invincible:deny flag aswell.

But players cannot seem to die?

Help?
