This is not the first time this has happened. I blew the first two times off as me missing something, but now I don't think so.

(Ignore the 11 second rt, forgot I had boxes.)

You leap from hiding to attack!
You swing a waraxe at a burly reiver!
AS: +254 vs DS: +106 with AvD: +23 + d100 roll: +21 = +192
... and hit for 44 points of damage!
Whoosh! Several ribs driven into lungs.
The burly reiver is stunned!
Roundtime: 11 sec.

A burly reiver turns to dust.

Yes, there was only one reiver here - I did not see another nor do I see one in my logs. No, another one didn't walk in. I was aiming at the neck - I missed the first time so it took multiple ambushes to kill it (too lazy to change my aim from the neck). I didn't kill him, in fact I never saw him die. He decayed in a matter of seconds after the hit shown here.

Just figured I'd post it here since I wasn't sure how to actually bug it.
