Description

Crash occurs when the user attempts to open an anim blueprint containing the Ragdoll node, when Immediate Physics is disabled.

Steps to Reproduce
  1. Open QAGame in editor.
  2. Enable the Immediate Mode Physics plugin.
  3. Restart the editor.
  4. Create an anim blueprint (I based mine on UE4_Mannequin_Skeleton).
  5. Add a Ragdoll node to the Anim Graph and wire it to the Final Animation Pose.
  6. Disable the Immediate Mode Physics plugin.
  7. Restart the editor.
  8. Open the anim blueprint you created.

RESULT

Crash.
