Preventing moveable objects from resetting upon level re-entry

[bleakraven]

Hey guys!

I've run into a problem with my custom story. At some point in map1, there is a stack of moveable boxes hiding a door. If the player messes with these boxes and goes out to map2 and then comes back to map1, the boxes will not remember the place the player left them at and instead will be blocking the door again.

Is there a way to prevent this or to allow the game to "remember" where the player left these boxes at?

Thanks
