NPC problem

I have a NPC problem.

Why don’t the TF 2 Heavy stand up?
I tried using the Keep Upright tool, with no luck.

The TF2 characters aren’t NPCs, they’re ragdolls.

Okay, so do I make a rag doll Stand up ?

Use the physgun.
Grab the head, pull it up, then freeze it.
Go from there until it looks like he is standing up.
