How to change a world.

Hello Guys,

i have a problem with my Handy Game.
I finished my Start Menu but if i try to open the first level it stops the tick event and the gui are still there.

Start Without “Open Level”

The Main Men has been removed but the level doesnt load.

Start With “Open Level”

The Level loads but the Main Menu is still there and the ingame ui wasnt added to the viewport.
