I'm not sure if you guys already figured it out, but here anyway: after you beat the game, the counter of net worth untill you level up shows HOW MUCH MORE YOU NEED, not THIS IS THE AMOUNT YOU NEED. And for those people who also beat the game and say MISSION is requierd for next level, that was either during a freelance mission, or you loaded from an autosave. If you loaded from an autosave, just load from the latest non-autosave. I think why it dose that because it usually autosaves in the campaign missions, so it thinks you still need to complete THAT mission. Hope i helped...
