Input.touchCount do not detect multitouch in iOS, but works fine for android

I am working on a project with a multiple of scenes in it. Problem is that one scene does not detect more than 1 touch in iOS device, but works fine for all android devices.

e.g.

void Update() { Debug.Log("touchCount: " + Input.touchCount); }

This function always returns 0 or 1, but only in that specific scene. I'm assuming something in the scene is affecting Unity's Input class. I still don't have any idea why I can't get more than one touch on an iOS device.

NGUI is being used so maybe it has to do something with it? Please advise
