having the same issue. Unity 2019.4.29f1. Works fine in the first scene, when the next scene loads it gets messed up the same way with an error message:
NullReferenceException: Object reference not set to an instance of an object DarkTonic.CoreGameKit.EditorScripts.PoolBossInspector.OnInspectorGUI () (at Assets/Plugins/Editor/DarkTonic/CoreGameKit/PoolBoss/PoolBossInspector.cs:781) UnityEditor.UIElements.InspectorElement+<>c__DisplayClass58_0.<CreateIMGUIInspectorFromEditor>b__0 () (at <3d9f46ac475f4fa9a3b71bacf80244a8>:0) UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)
I deleted everything related to dark tonic, editor stuff, plugins, assets, master audio, core game kit, reimported everything and it still bugs out. Anything in particular i can take a look at?
It works until i change the scene.
Ah wait, i screwed up the project and PERHAPS i installed CGK from the asset store. What files need an update besides poolableinfo, poolboss and poolbossinspector since i don't want to screw up again (if i did, i can't remember if i installed from the package or from the store)?
Sorry for the fuss, publisher's waiting for QA and i need to optimize the pools to finish the five years work.
