Bug description

I can create a task in a ticket and assign it to somebody.

But!
If the assigment tecnition is not assign to the ticket in any role - he cannot know about that task (and see, and check/uncheck the checkbox).
Also if the tecnition is assigned to the ticket, he can not check or uncheck the ticket task that was be assignet to him in case if "Home > Administration > Profiles > Assistance > FOLLOWUPS / TASKS > Ticket tasks / UPDATE ALL" is unchecked. But if it is checked - he can also check or uncheck ticket tasks that is notassignet to him.

So please give me any reason to assign the tasks!
I've already tired to fight with the understanding of logical roads of the system.
