Steps to reproduce:
1) Open the latest attached project.
2) Open scene 'TestScene'.
3) Press play.

The Test.cs script is used to convert members of an instance of a serializable class MyClass() to JSON format and back twice. During the first conversion JsonUtility.FromJson serializes to the JSON file as [0,1,0] rather than [false,true,false], therefore, JsonUtility.ToJson will not read the values correctly when converting for the second time and will output the default 'false' values.
