@Cloud please add a isSDK && instanceof Listener && getEventListeners().contains(this) to the internal onStart() so as to prompt the user if they implemented the right stuff but forgot to register the event listener. It won't handle all cases if the dev decides to abstract the listener to non-AbstractScript class, but it'll handle 99% of them. It's a dumb issue we should help devs debug.

Implemented for next release.
