Hey, I am currently using the latest Unity version 2019.1.0f2 with Cinemachine 2.3.3 we have a couple of camera objects (Cinemachine ones -- both are virtual cameras) that we'd like to add Post Processing to. They are both inside a prefab, I navigate to the cameras, choose "Add Extension" and then choose the PostProcessing option. I save my changes to the prefab and add the profile I want. I save again. I exit prefab mode then open the prefab again. All the PostProcessing extensions are automatically removed and replaced with "Missing Script" error. I removed Cinemachine from the project (from PackMan) and installed it again. Same issue. We tried on different devices so far and it is the same result on this project. Any idea what the issue might be? Thanks.
