If that line says 0x8b for each of the Object Data for that object, then it's base game compatible without you having to fix anything. If even one of them says 0x8c, you should consider re-creating the object if you want to make sure it works in all versions of the game (unless it's something like a bookcase which you want to have the University specific functions for college, for example).
