Hi everyone, Our game is to publish in WP8 platform. I upgraded my Unity to 4.3.3 this afternoon. After this, whenever I run the game(maybe especially when the game loads a new scene), there are countless strange message displayed in the output of VS2012. They are something like this below: Incorrectly unloaded MonoBehaviour class 'UIAnchor' in prefab 'b_BackgroundCenter' during GarbageCollectUnusedAssets. The Object will be reloaded from disk, to fix this properly keep a reference to the MonoBehaviour directly instead of the game object or other component. While the output keep on saying these, the game lag heavily. What's wrong? Has something to do with 4.3.3? Any help is appreciated!!
