I'll let you in, but we'll leave it at that. We need a fair amount of objectives for each person. I reckon we should restart the final mission. We haven't created a schedule yet, and Chips may of ruined the balance of objectives.
Now, let's think of a schedule.
If we split the objectives up equally, we would get 13 for each player. (rounded up)
Now, we can either:
A) Increase the amount of objectives in the mission. Maybe to 90, perhaps 100. If there was 90 objectibes, each player would get 2 more objectives (15) and 17 if we were to do 100 objectives. Problem with this is the game would be prone to crashes and bugs.
B) Some people can give away some of their objectives to other players if they choose to. This means one player would get more objectives, but the other will lose some of their objectives.
