Keeping Ragdolls [GMOD13]

This is a stupid question that I’d rather not make a thread for, but I haven’t found any answers through search.

What is the console command to keep ragdolls when NPCs are killed in Gmod13?

I know it was ai_keepragdolls at some point but that no longer works, nor is there an option in the spawn menu to do so.

Like I said, I didn’t really want to make a thread but the Gmod 13 section is for bugs and requests, and there isn’t some megathread for “dumb questions that don’t deserve a thread”.
