coop map problem

[FearlessGoat]

Hi guys,
I have been working on a coop map and I have a problem with the level transition. The level completes fine but is stuck in an endless loop. You have to manually select return to hub. Is there an easy way to trigger the transition to go automatically to the hub keeping the users day status intact?

Here is the map if anyone is kind enough to look at it.
