How to edit this caterpillar script so that those who are knocked out stay in line

I'm using fukuyama's Caterpillar script. Works fine aside from this. When my main character gets knocked out (or anyone) he disappears from the caterpillar line. I'd like it so that even when a character is knocked out, they still follow you. This is because I need the main character to be at the front of the line all the time, for the (plot text) scripts to make sense (eg. Main character is talking, but he's nowhere to be found.)

So could somebody edit this script so that when a character dies, they don't disappear? It seems to be rather simple. I tried editing it but no luck whatsoever.

Here's the script

Thanks in advance!
 
Unfortunately, that script gives me a couple errors. It apparently doesn't work with SDK 2.2, which is what i'm using. It also said something about the stack level being too deep on line 445 I believe.
