Hi Fallingman,

Your assets contain multiple errors that fail the cook, if you open up the log yourself and search for error: you will find them. Here are the ones that should be fixed;

  • UE4Editor-Cmd: [2017.02.19-17.19.40:732][ 0]LogBlueprint:Error: [Compiler PersistentLevel.Level_0] Error Couldn't find object for bound event node K2Node_ActorBoundEvent_2 from Source: /Game/Maps/Level_0.Level_0:PersistentLevel.Level_0
  • UE4Editor-Cmd: [2017.02.19-17.23.03:744][ 0]LogBlueprint:Error: [Compiler Tutorial_Widget] Error The type of Object is undetermined. Connect something to K2Node_DynamicCast_7 to imply a specific type. from Source: /Game/Help/Tutorial_Widget.Tutorial_Widget
  • UE4Editor-Cmd: [2017.02.19-17.23.14:866][ 0]LogWindows:Error: Failed to find dependency index for BlueprintGeneratedClass /Game/Help/BP_Tutorial.BP_Tutorial_C (Blueprint /Game/Help/BP_Tutorial_Intro.BP_Tutorial_Intro)

Hope that helps. Cheers,
