Hello there,
I don't seems to find any solution to this but when I change the variable of the action, say adding one, the playmaker editor refuse to render anything when I clicked on any state that contains the action, generating errors like,
NullReferenceException: Object reference not set to an instance of an object
Assets.PlayMaker_Custom_Actions.LoadImageLocal.Reset () (at Assets/PlayMaker Custom Actions/LoadImageLocal.cs:37)
HutongGames.PlayMaker.ActionData.CreateAction (HutongGames.PlayMaker.Context context, Int32 actionIndex) (at C:/Users/Alex/Documents/Unity/Playmaker/Projects/Playmaker.source.unity/Assets/PlayMaker/Classes/ActionData.cs:893)
Any helps? I hate to remove actions before I can change them
