is it possible to undo a mass cancellation of group members? one of my helpers was trying to delete two people from our newsletter subscribers group & somehow managed to delete everyone since it is several hundred contacts, we would prefer not to have to re-join each contact manually, but so far i haven't been able to find a way to undo the action.

i tried doing an advanced search, for cancelled group memberships on the date that it happened, but it returned no results which seemed strange; i then broadened the date by several days but still no results. i also tried searching in the change log for changes done by that username, but it also returned no results - which makes me think that the advanced search is not very accurate, as i know that there should be results for these searches (unless i'm misunderstanding what it means).

we are running CiviCRM 2.2.1 in combination with 6.
