Video 2:
As you can see spawning on the edge/outside of the load range the mushroom isnt rendered.
The button i press is resetting the sequence as stated above it goes back 1 second and plays it.
When spawning in the range it will always work in game regardless if you go far and it completes then you come back.
Its something to do with where the player initially spawns in the world relative to the actor in question.
