I will submit this as a bug if it's a bug - I am not sure if it's just me. This is what I do:
* Fresh new unity project.
* Create an empty game object that runs 10 times in a loop. Each time, it's creating a game object copy from a PreFab, at a random spot. No problem. 10 cubes spread around.
* Editing the PreFab, and give it an untouched iTween MoveTo.
All works fine, all prefabs moves to 0,0,0 as expected, but the Console is giving me the warning:
NullReferenceException: Object reference not set to an instance of an object
iTween.LateUpdate () (at Assets/iTween/iTween.cs:6589)
- and it keeps on adding that error to the console, one and on, also after all is done.
