Null reference exception on start (do not disable scene reload *solved)

[N0Skillz]

Bumping this old thread since it is still relevant and have been trying to find a reason why Obi Particle Attachments (in my case) fail (they're not attached properly) when scene is reloaded, and since I feel there's a lack of direct info on how to resolve it, I'm attaching a screenshot from Project Settings inside the Unity Editor.
