I have done several missions several times and yet the task window still says I have to complete them. I don't know if I can continue to level up without finishing tasks, and right now I am at level 4, I think.
Before the last big patch, the mission window would put check marks by missions completed. Now, nothing has a check bar by it. I am wondering if that is because the game is not recognizing I have completed those tasks, and therefor no check box.
