The looping is caused by the way IWT works with Click to Move. I explain it here. Your slaves are basically running away and eventually turning around and running back because they received a command to interact again. The longer it takes for them to receive the command, the longer it takes for them to interact again, thus the longer loops.

It looks like you are sending it enough at the start to get them to run around, but then you stop sending it for longer periods as you spam. Send your IWT command more often/consistantly to shorten the delay between runoffs and reacquiring. If that doesn't do it, it may be because you are at target dummies and they aren't actually ABLE to click a valid location until they get out from under the dummies, which I also address in that link. In which case, you'll have to futz with the camera angels.
