What is the unity reference helper script?

I upgraded my project from 5.0 to 5.3 and these scripts got auto added to some of my objects.

I removed some of them out of curiosity. Now when loading, 1 out of 5 times half of my links are broken and set to ‘none’.

What is this and how come google returns nothing? And if they are important how come you can remove them?

Thanks

You most likely are using Aron Granberg’s A* pathfinding framework. This script most likely should help that system to keep track of that gameobject and store additional instance information.
