I’ve very new to unity and am wondering how to tell what this is referring to. Its clearly an animation issue but how can I tell which object its even referring to? Never mind which specific animation.
I got the same error and fixed it with my crazy hacking skills: I opened another project and then opened my original project and the error was gone. So yeah, I agree with the guy above me, this error is BS.
