I have one more question... how to save event that was morphen into something else? When I reenter map, that event is like the one before morph.
Also, I think I found a bug. You can't transform spawned event using "this._eventId" (Ritter.transformEvent(this._eventId, 1, 38)) - it just dissappear after that. It works for morphing "this event" which is already on the map.
