From the battle log, you can see I got an attack from the Ashen Oracle.
Two line above that log, you see the Ashen Oracle is killed.
I'm pretty sure that there's no other Ashen Oracle around or close by, so the source can only come from the dead Oracle.
I'm just standing next to the mob, and also from the active skills, you can see I'm using melee attacks. I'm so close by that the attack should have been immediately hit me before the Oracle dies if it did take the shot.
It is not a case that the ranged attack is on the way toward me so I got the shot after the Oracle got killed. I notice when I'm being from a range, I can got the shot after the mob being killed, but my case is with melee distance.
Probably there's some issue along with the problem when ranged mob got knockback, (Bash, Whirlwind, Kick), they will shot at an incredible speed.
Hope you understand what I'm trying to describe.
