When you use a statuette there is a brief delay before alignments change, so if you turn back into a human and immediately attack a normally hostile creature, they may still be friendly.
Ah, that's exactly what I did. I attacked an orc the second I transformed, and he reacted as if he had been friendly, and was now hostile.
Thank you very much for the help, I guess I'll have to reload to the latest save before that happened.
