I'm no good at scripting but...
open the script used for the rag-doll using notepad.
There should be a command here call
"timergreater"
It should have some numbers next to it. Example
"timergreater=10000".
I'm going to assume this means after about 10 secs the body will disappear. Change this to a higher number or 0 or removed the command and see if it works.
Again, I'm no good at scripting and this is just a theory but check it out...
I tried...Good luck !
