Description

Using Execute Console Command nodes to record and play back a demo is causing a crash in standalone. Using the console commands themselves does not seem to cause the same crash to occur.

Steps to Reproduce
  1. Open the editor (FirstPersonProject)
  2. Open the FirstPersonCharacter blueprint
  3. Recreate the blueprint in the attached screenshot
  4. Play in Standalone
  5. Press 1 to start the demo recording
  6. Move around a bit
  7. Press 2 to stop the recording
  8. Press 3 to play the recording

Result: Camera snaps to the world origin and player can no longer move. Crash occurs upon exiting standalone

Expected: Demo would play and no crash would occur
