A scripted object has a different serialization layout when loading

[broseidon91]

When building for Android, I get these runtime errors

The referenced script (Unknown) on this Behaviour is missing!

I was able to reproduce this in a new project using Unity 2020.3.23f1 and SreamingImageSequence 0.14.2-preview

1. Create a new project (2020.3.23f1)
2. Add StreamingImageSequence package to the project (v0.14.2-preview) via git
3. Add your PNG sequence into a new folder in the project (notably, not in streaming assets)
4. Create a canvas object in your scene. Create a child gameobject of that canvas and add an Image component
5. On the canvas, add a PlayableDirector component
6. Open the Timeline window and select the Canvas. When prompted to create an asset, do so.
7. Drag your PNG sequence folder into the timeline (or create a Streaming Image Sequence track)
8. Drag the gameobject with the image component into the track's Streaming Image Sequence Renderer reference. It will add the component and attach the reference.
9. Make sure your build settings indicate Android
10. Build to device
11. Open terminal and type adb logcat -s Unity and witness the errors
12. the sequence will not play

Thank you for the report.

Just to let you know though, playing non-StreamingAssets images in runtime is not supported yet.
