Forgotten tasks, sweeping and mopping

I am not sure if there is a limit or if they are just being forgotten. (A limit, as in, too many tasks to fit into the task-list of errands "to do".)

I have several tasks that are being ignored, completely, by everyone and have no "errand list".

These are all priority 9 and "!", which just get ignored. Both for sweeping and mopping.

If there is a limit, then they should NOT be tagged as errands, if they are not in a list of tasks. They have to be cleared before they can be done. Changing priority does not put them back into a task-list to be done. They continue to get ignored.
