The only time I ever have slaves run away is when I have a mod with "Follow after combat" turned on. I used to have the issue all the time, but I turned that option OFF on my mod (multiboxer v2 right now) and I have never, EVER had that happen since. Now I just spam my follow key periodically and never worry about following after combat automatically.

I don't want to use a strobe feature as a lot of times ill hit the down arrow to stop just my slaves from following to fight a boss or something and I don't want them to a) start following again randomly or b) have to remember to turn the strobe off or something
