Anyone have an idea what this is? Please help :frowning: I cannot tell you what I have done differently to yesterday where everything “worked fine” …

Thanks already!

Found the error source… it’s my Character Blueprint… yay… quick fingers… deleted the blueprint and there go the controls… Let’s do it again! yay … Good morning everyone!
