I don’t know myself, i have the same problem. Mine is: LogValkyrieValidation: Error: [16] Found disallowed object type /Game/Balance/Physics/Materials/PhysData\_Foliage.PhysData\_Foliage I’ve tried twice now to fix it, even going threw countless files and yet nothing, from what i understand its a glitch so it should be fixed soon ---

I am having the same issue with my own project not the tutorial. I cant find the objects to delete using outliner. ---

Hello I got a similar error performing an example [Capture the Flag](https://dev.epicgames.com/documentation/en-us/uefn/capture-the-flag-in-unreal-editor-for-fortnite) . LogValkyrieValidation: Error: [16] Found disallowed object type /Game/Environments/Sets/IceCastle/Meshes/S\_IceCastle\_Wall1.S\_IceCastle\_Wall1 Moreover, the error did not occur immediately. First, I marked up several walls on the stage (20-30) and started the session – everything worked and there was no error. When I finished the scene and tried to start the session, I got an error. I understand which asset is causing the problem, but to remove or replace it with another one is a problem for me because there are more than 100 of them, we will have to completely redo the scene. I hope that this information will help you in diagnosing the problem. ---

Getting the same project invalid/ disallowed object errors on project which previously worked fine. Used only assets included in the fortnight folder. Super annoying, was really looking forward to this tool set. ---

This has happened to me before, but with a deletable object, but it happened again and with one of the Fortnite core materials. (which I couldn’t delete) ---

You bet, seems to be a very common issue currently. Other than using error code and outliner to try and find/delete items the only other suggestion I have found is wait for a new release of program. ---
