I wanted to get rid of a pack horse and instead of just releasing it I casted energy bolt on it. Just that second I casted the spell on it I got guard whacked. Was it always this way or is this a bug ? That was at the stable in Britain. Later I did the same in my house. I casted energy bolt on my packy and killed it. After I killed it I was flagged grey. Btw, that's on Siege Perilous.
