I am using 2018.1. Cinemachine plugin is throwing some errors in console, such as: "Assets/Cinemachine/PostFX/CinemachinePostProcessing.cs(160,22): error CS0246: The type or namespace name `PostProcessVolume' could not be found. Are you missing an assembly reference?" Besides that, Cinemachine editor menu options do not exist. It's like the entire Unity install has no idea Cinemachine exists. Yet it sits in the Assets folder. This is a total fail. I can't even break Cinemachine because it doesn't show up.
