-unfortunately, as you can see, we need a hack when creating new blueprints. Generating a Blueprint with the same name of another one will trigger a crash. We are investigating a better api to avoid that tricky exception.
+Always take into account that creating a Blueprint (of any kind)  with a name of an existing one, will trigger an error.
+If ue.find_asset() succeeds, we destroy the already existing asset. 
 
 Once the blueprint is created, we need to assign a custom event 'DoAttack' (triggered when the Kaiju is near a Pawn), anpther one called 'Boring' (triggered when the kaiju is stationary/idle for more than 10 seconds), 2 bool variables (Attack, Bored) and a float one (Speed):
