Just updated to latest and getting compile error when building for Windows Phone. I have been test with my phone all night until I applied the update.
Assets/NGUI/Scripts/Internal/PropertyReference.cs(167,17): error CS0103: The name `mField' does not exist in the current context
Assets/NGUI/Scripts/Internal/PropertyReference.cs(168,17): error CS0103: The name `mProperty' does not exist in the current context
It appears that the issue might be this:
#if UNITY_EDITOR || (!UNITY_FLASH && !NETFX_CORE && !UNITY_WP8)
#define REFLECTION_SUPPORT
#endif
