Description

Crash occurs when the user attempts to drive a non-Vehicle pawn (using a Vehicle Wheel Movement component) with the Torque Curve flattened to 0.

I was not able to reproduce this crash when I tried this with a WheeledVehicle class.

Steps to Reproduce
  1. Download and extract the linked project.
  2. Open the project in editor.
  3. Play in viewport.
  4. Press W.

RESULT:

Crash.
