    I have a fairly simple custom class that I'm trying to display a list of in a custom inspector. Here is the custom class:
    Code (CSharp):
    1. [Serializable]
    2. public class TransformTarget
    3. {
    4.     [SerializeField]
    5.     private Transform target;
    6.  
    7.     [SerializeField]
    8.     private Vector2 influence = Vector2.one;
    9.  
    10.     [SerializeField]
    11.     private Vector2 offset = Vector2.zero;
    12.  
    13.     public TransformTarget(Transform target)
    14.         : base()
    15.     {
    16.         this.Target = target;
    17.     }
    18.  
    19.     public TransformTarget(Transform target, Vector2 offset, Vector2 influence)
    20.     {
    21.         this.Target = target;
    22.         this.Offset = offset;
    23.         this.Influence = influence;
    24.     }
    25.  
    26.     public Transform Target { get => this.target; set => this.target = value; }
    27.  
    28.     public Vector2 Offset { get => this.offset; set => this.offset = value; }
    29.  
    30.     public Vector2 Influence { get => this.influence; set => this.influence = new Vector2(Mathf.Clamp01(value.x), Mathf.Clamp01(value.y)); }
    31. }
    Then I have a MonoBehaviour that contains 'List<TransformTarget> cameraTargets'. I have a custom inspector made using uxml that has a property field with 'cameraTargets' as the binding key.

    It displays just fine, exactly how it should, but any sort of modification and it throws an error:
    Code (CSharp):
    1. ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
    2. Parameter name: index

    Any idea what's going wrong?
