HIT deleted after rescheduling
I discovered you CAN "Remove from week" a HIT item (no objective, role, or list). However, if you unschedule it, then reschedule it, weekplan just deletes it altogether. Cannot even search for it.
Add a new HIT
Drag to schedule
Edit task and click "Remove from week" (returns to HIT list)
Now drag to schedule again (poof, it's gone, totally deleted).
