NPC melee attacks hit unintended target (guard) instead of intended target (me) in specific situation
In OpenMW I can stand with a guard between me and the assassin and the assassin will hit the guard. In vanilla the assassin hits me instead. The attack range also seems more aggressive in vanilla but I did not confirm this.
Because guards don't pick up on the assassin aggro like they do with creature aggro, you can probably use this to kill guards without getting a bounty, which is problematic.
