I’m trying to test my game in the Automation tab of the Session Frontend window and keep getting several errors followed by UE4 closing completely. All the errors I get are in the project section but most of the errors seem to be related to blueprints that I’ve deleted and no longer need or use. The game compiles and packages without any issues but when I run this tool I get problems. The error is basically “Failed to compile invalid blueprint, or blueprint parent no longer exists.”
How can I let UE know that the blueprint is no longer needed?
