Well it has been like a decade sine i use the engine, and to change map in order to change map i do clean like remove all actors in game else it just pops me an error, I wonder 
is there another way to do so? I know there is console command change map but that fails if you don’t remove all actors and clear collect the garbage i also have to do a little trick that you have to trigger the change map open level by timer… . A mess any idea on how to correctly do that?
