Mr.Mo made a Squad Based Action Battle System. It allows party members to follow the leader around(like a caterpillar script). You can find it
Here
That is the Lite Version. I can't seem to find his EvE (Event vs. Event) version of the SBABS, but you might want to search for it.
By the way, you might want to get a rid of the Caterpillar script, they are probably incompatable with the SBABS.
