    When using the Execute Function action, when I click the “Select Method” button in the action node I get the following error. I’ve used this action plenty of times before, and it’s still working in graphs using it. However, today all of the sudden it seems to no longer be behaving properly. I can’t select any methods via this action.

    Hello,

    It seems that you have a ‘missing’ monobehaviour script attached in your gameobject. Can you please confirm if that is indeed the case?

    Thank you.

    Oof, yeah that was it. If it was a snake it would have bit me. Thanks for your help!
