How do i keep omnifocus from deleting a task once it's marked as complete? I'm not sure if i've done something wrong, but I marked off a few tasks complete before I shut off my laptop last night, and when I turned it back on this morning the completed tasks were gone. I use omnifocus to organize my homework, and within the notes section of tasks I write references for my papers, so even though the task is complete, i still need access to the notes affiliated with the tasks, so I do not want omnifocus to delete the task once it has been completed.
Cheers
