Weird UI when deleting a task

[abegel]

I have a family called AndrewFam. I have one parent (P) and two children (A and B). I created a task and clicked on the task in a browser with child A logged in. A's browser shows the details of the task and a button to Accept it. On P's browser, I then select the task in the Unclaimed view and when the task details show up, I delete the task. A's browser still shows the task detail view and the accept button. If I click on Accept, the application correctly shows that A did not accept the task (which is no longer in the system).

So, the behavior of the app is correct, however, given the amazing responsiveness of the app's UI to actions taken by other family members, I feel that the app should display something on A's browser to indicate that the current task detail page is no longer valid, removes the Accept button, and lets A click on the Back button to go back to the original dashboard screen.
