Now I´ve the same problems. It falls
trough the floor after level load.

I play a little with it.

[edit]

Duuhh, it´s a bit "spagetthicode", but it works.

The theory: Events calling functions in another kind as key-assigns...
Look at the manual at events.
When I was reading that, another way to call the function came into my mind...

I´ve an action on an entity, by an impact it calls a function.
This function set a variable to 1.

Another function, it´s called by main(), contains a while loop.
It´s checking if the variable is set to one.

--> while(variable == 0){wait(1);)

After that comes the new level load.

So you must call the level load indirectly, not with an event....

I hope you understand that all
