I have searched the forums a little and have tried to remove this line -

+DefaultChannelResponses=(Channel=ECC_EngineTraceChannel1,Name=“DefaultProjectile”,DefaultResponse=ECR_Block,bTraceType=False,bStaticObject=False)

From the DefaultEngine.ini however, unlike with the user that suggested it, it does not work for me. I have uploaded the logs and DMP to mediafire and will try again to upload them here however that didnt work last time.

If you need anymore info about my etc, please let me know and i will provide them asap.

I hope i can fix this soon as the project is due in on monday as a college assignment :s

Thanks

Hey -

Do you have a blueprint named EndLights in the project? If so try moving that out of the project temporarily and then try to reopen the project. If this does work for you, you can try to move the blueprint back in or recreate the blueprint.

Cheers

That’s solved it, spot on! Thank you sir :slight_smile:

Hi ,

We’re wondering if the crash you were encountering is the sign of some larger issue. You don’t happen to have the broken content on hand, do you?

We’d like to take a look ourselves and see if we can figure out what happened. It’d be nice to fix the root cause of whatever landed you here.
