Why won't particles prewarm properly in a wind zone?

I have set up a particle system to act like clouds that become sucked into a star in the middle. But the thing is, they won't prewarm properly when I launch the game!

You may think that this is not possible, but it works, only after I have re-assigned the "wind zone" and "particle system" components to completly new gameobjects. But when I restart my project, it breaks and I have to redo everything to make it work when I start the game.

Why is it doing this? How can I avoid it? Is it a bug? You decide.

Edit: I have boiled it down where I just make a new copy of the GameObject with the Wind Zone and remove the old GameObject to make it work again. But it breaks once again when I reload the project. Are Wind Zones simply not being saved?
