Seems a bit odd. I had to restart Unity to have this work?

I found that I had to restart unity in order to see correct results using the script on the child object as opposed to having the script on the parent?

Is this normal behavior from unity?

Thanks

What are you trying to accomplish with the script? Sometimes things break and unity needs a restart but not normally.

This sounds like a serialization issue.
It does happen from time to time but reloading the scene or restarting Unity should fix things.
Sometimes it can even be as easy as just resetting the component on the object.

Instead of restarting Unity, you can jump to Play mode and then go back to Edit mode may helps.
