from what i've found and read; If you don't have all of the objects in your library, then the stock Zero will be used to replace the missing objects. So if you open the mission in MB and it says that such and such object is missing, take note of it. close MB. then add that object.
i'm sure its covered somewhere. but thats what i've found. normally everythng else will work fine.
