I am getting negative karma due to "overdue tasks", but there are no overdue tasks on my to-do list!
I receive negative 3 karma consistently, but I have completed all of my overdue tasks - none show up in my inbox, and I have checked to be sure that it is searching for overdue tasks.
Do tasks that I have assigned to others count against my karma? Is that why they are not showing up on my list, but counting against me? :-S
