Very new multi-boxer here-- planning on a 4 warlock 1 priest team.

I'm trying to use the "No focus manifesto" playing style where everyone does a /cast [target=targettarget] for all their spells. They all should just keep the brain targeted the whole time so their spells work properly.

Anyway, I ventured into RFC with my guys and kept having to retarget my brain. I thought I was going crazy or hitting the wrong keys or something, so I installed xperl-unitframes on the brain so I could see the target of all party members.

Sure enough, all my clones are changing targets randomly when mobs get close to them and I can't figure out why. Only the brain has mods loaded, all other copies are running vanilla.

Any ideas on how to turn this off? They all have my brain targeted, they cast a spell or two, but it looks like if they get struck (possibly by aoe) or a mob just gets close to them they switch to target the mob instead of my brain.

I found this old thread asking the same question but it never got an answer, and my issue is exactly the same:
