This collider has some illegal parameters. Choose 'Reset' in the component popup menu to fix it

先看一下面的一个帖子：http://forum.unity3d.com/threads/168714-Error-when-adding-a-BoxCollider-component。原文如下：

1 After calling myGamObject.AddComponent<BoxCollider>() I
get the error "This collider has some illegal parameters. Choose 'Reset' in the component popup menu to fix it" followed by "abb.IsValid()" and then "!isFinite(outDistanceForSort)", "!IsFinite(OutDistanceAlongView)" being printed over and over again.

There are no popup menus to click, like the error suggests. What is causing this and how do I fix
it?

2 Well I found the problem, but not the solution. myGamebject
is created by Instantiating another GameObject that was loaded using Resources.Load("path to mesh"). It looks like the mesh being loaded is getting corrupted, which is strange because I load it in other parts of the code in the same way without issue. The
corruption is screwing up the scaling of the transform and the scale values are either astronomical or NaN.

edit: Finally found the issue. If you set a game object's transform's parent to a transform that already
has a parent, the game object's scale flips out.
