Title: Valid-mutation enforcement

Turns out that the only time it actually checked "valid" was when you didn't have a prevailing mutation-category. That's a Bug as it effectively turned generimutagen into categorized mutagen for your
strongest category.

This imposes validity checks throughout the non-targeted mutation procedure, fixing that bug.
