I told my Sedna to move back because three DGs were coming in. She turned, took a step, stopped, and started fighting them. I did not order her to stop, nor did I click on any of the DGs that were coming in. My mouse was left where I told her to move, and only wasd touched my fingers. I could only stare in amazement as she died.
Also, it's damn annoying to have your minions attack flags instead of, you know, enemies.
