========== END OF STACKTRACE ===========

The call stacks has some difference everytime, but the top of the stack is always Transform::SetCacheDirty function.

it only happens when our game is switching scenes, but not everytime.

We were using Application.LoadLevelAsync() to load our scene, I am not sure if this is a problem.

And We cannot reproduce this in editor mode.

I have no idea what should do to stop this crash. Can anyone help?

Thanks.
