I am unable to cast Animate Dead. It says I have no uses or preparations left. I cleared out my Override folder and downloaded a fresh domain.2da, but still no luck.

Confirmed.

I know what the problem is, but "fixing" it may just make the spell fail after it's cast anyways. It's going to remain as-is until further notice.

This should be fixed after the next reset, which may be up to 36 hours from now.
