I also have this problem. Perhaps it is associated with a global variable created order. When debugging, The order in which the call is GGrassRenderingNotification->GLandscapeTextureBakingNotification->GShaderCompilingNotification->FSourceCodeNavigationImpl->GTextureStreamingNotification and TArray FTickableEditorObject::TickableObjects. At this time, TickableObjects has been reset. It was compiled in vs2013.
