Exception during PIE

Hey i get this exception during PIE.


The editor freezes for long seconds and stops responding.


Without having the context of your project, it’s difficult to diagnose this issue. However, I see this error message:

NewObject->IsA(this->GeneratedClass) [File:D:\BuildFarm\buildmachine_++UE4+Release-4.11\Engine\Source\Runtime\Engine\Private\Blueprint.cpp] [Line: 669]
Type mismatch: Expected DevLevel_C, Found LevelScriptBlueprint

Could you provide some more information:

  • Could you provide a screenshot of the blueprint that contains the references mentioned in the above error?
  • Do you have any way to reproduce this in a clean project?

It’ an empty blueprint. I can’t reproduce this issue in a clean project. I don’t know what causes this. I posted this here hoping that someone can help me fix this :slight_smile:

What sort of project is it? Are you using any templates?

It’s a C++ project a thirdperson shooter kind of. No i haven’t used any templates

Could you please zip up the project and upload it to Dropbox? You can provide a link to the project via PM through the forums: https://forums.unrealengine.com/member.php?160394-Sean-Flint

Also, is this the same project that you are reporting the crash on in this post:
Random crash in 4.11 - Programming & Scripting - Unreal Engine Forums ?

Yes it’s the same project i sent the project files via google drive in pm.

Thank you, I am investigating this issue and will respond to both of your posts as soon as I have information.

I was unable to see this exception occurring during PIE. Was there a specific action you were performing when you were seeing this?
