Don't you just hate it when FA tells you that you can't add any more objects of "that type." Even though that means you can't add anything at all...However, I found away around that, creating over 100k missions, hell I even squeezed out a 180 something K mission. So here is how you get around it.
1. Create your mission as
you want, going until you reach the buffer. Then save it as something, let's
used TEST for example.
2. Exit the game and restart it
3. Reload your mission and add more objects until you are satisified or until
you reach the next buffer. Usually you won't need to go that far.
4. Save it as a different name such as TEST1. If this is the final version,
delete TEST and rename TEST1 to TEST. You know how have your mission.
I don't know the limit on
buffer's but exceeding two is tough and usually you can't add anything after
the second.
Contact me if you have any troubles.
