This is not an ultimate fix for the issue at hand if wanting to retain the data, code, blueprint of the Player Character.
There seemed to be an issue with the Player Character I had. When I started my project I saved a copy of my blank Player Character.
This is what I did to fix the above issue:
- Delete the Player Character that caused the test / simulate to load only at spawn
- Delete the original Player Start
- Add a Player Character with no meshes linked
- Add a new Player Start
