A custom editor script is causing the scene to become corrupted, losing references to all scripts

I made a custom editor script that exposes a button. Upon clicking the button all Monobehaviors on the GameObject implementing a certain interface are gathered, and a TextAsset is extracted from each one through the interface and then added to a single Monobehavior's public array of TextAssets. However, clicking the button causes the scene to become corrupted the next time I run Play. Reimport-All always fixes the problem, but the entire process causes huge delays in development. Here are the editor scripts:

Code (CSharp):

1. using UnityEngine;
2. using Panda;
3.  
4. [RequireComponent(typeof(PandaBehaviour))]
5. public class BehaviorTreeAILinkerAggregator : MonoBehaviour
6. {
7.     public void ImportAILinkers()
8.     {
9.         var ai = GetComponent<PandaBehaviour>();
10.  
11.         var aiLinkers = GetComponents<IBehaviorTreeAILinker>();
12.         var numAILinkers = aiLinkers.Length;
13.         ai.scripts = new TextAsset[numAILinkers];
14.         for (var i = 0; i < numAILinkers; i++)
15.         {
16.             var aiLinker = aiLinkers[i];
17.             ai.scripts[i] = aiLinker.GetAI();
18.         }
19.     }
20. }

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3.  
4. [CustomEditor(typeof(BehaviorTreeAILinkerAggregator))]
5. public class BehaviorTreeAILinkerAggregatorEditor : Editor
6. {
7.     public override void OnInspectorGUI()
8.     {
9.         DrawDefaultInspector();
10.  
11.         BehaviorTreeAILinkerAggregator script = (BehaviorTreeAILinkerAggregator)target;
12.         if (GUILayout.Button("Import AI Linkers"))
13.         {
14.             script.ImportAILinkers();
15.         }
16.     }
17. }

Code (CSharp):

1. using UnityEngine;
2. using Unity.Entities;
3.  
4. [RequireComponent(typeof(EntityStore))]
5. [RequireComponent(typeof(BehaviorTreeAILinkerAggregator))]
6. public abstract class BehaviorTreeAILinker : MonoBehaviour, IBehaviorTreeAILinker
7. {
8.     [SerializeField]
9.     private TextAsset ai;
10.  
11.     protected EntityManager EM
12.     {
13.         get;
14.         private set;
15.     }
16.  
17.     protected Entity User
18.     {
19.         get;
20.         private set;
21.     }
22.  
23.     public TextAsset GetAI()
24.     {
25.         return ai;
26.     }
27.  
28.     protected void CreateMessage<T>(T message)
29.         where T : struct, IComponentData
30.     {
31.         var messageEntity = EM.CreateEntity();
32.         EM.AddComponentData(messageEntity, message);
33.         EM.AddComponentData(messageEntity, new MessagingEnd());
34.     }
35.  
36.     protected virtual void Start()
37.     {
38.         EM = World.DefaultGameObjectInjectionWorld.EntityManager;
39.         User = GetComponent<EntityStore>().entity;
40.     }
41. }

 

Anyone encountered this issue before? This is happening quite frequently to me
