    Hi,

    could we have a bug report to look at? Which Unity version are you on? Unity should automatically reload textures in most cases.

    Found the cause of the problem, for some reason, window phone handle private static variable differently. I've cached a prefab in a static variable and instantiate it when back to main menu scene. It works flawlessly in Android and iOS, but when port to Window, when doing the same thing, some of the textures just went missing. Please do note that, I've load texture on demand via Resources.Load function.

    I'm also notice that when tab in and tab out from the windows phone app, it will clear the scene memory's texture ( check via profiler ) which cause me some trouble to re-code to handle such behavior.

    I'll try to send a bug report for it, the project size is huge, i need some time to trim the project size.

    This **might** be a known issue. Normally, when Unity loads a new scene, it unloads all assets. In order not to destroy it, we need to know it's still needed. In case of Mono platforms, we have ability to walk through the object graph and see that the managed objects are still alive. However, on .NET we do not have such an ability, so the static variables are not checked. We have a few ideas of how we can fix it in the future, but I can give no promises of when it's going to be implemented.

    If you want to tell Unity not to unload an asset when you load a level, use this method:
