  1. Resolution Note:

    Thanks for reaching out. The supported version is com.unity.behavior, not com.unity.muse.behavior, which was an experimental package and is no longer supported. There shouldn't be any nodes that exist in com.unity.muse.behavior and are missing in com.unity.behavior, please reach out in the forum if you need any help with your specific use case: https://discussions.unity.com/tag/behavior
