Title: How to recover deleted (?) activity
ThreadText: # How to recover deleted (?) activity
  
  (Asked by: username_0 on 2018-01-06)
  
  I think I may have deleted a bunch of activities by accident. Here's what seems to have happened:
  
  1. I had "Activity X" scheduled to occur every Saturday from 6/10/17 to 12/30/17
  2. As 2017 rolled along, each Activity was customized as a stand-alone "just this one" edit week by week. This gave me lots of individual past activities as desired.
  3. Because I needed to keep doing this through 3/31/18, I went to the entry for 12/30/17 and extended its "stop repeating" date to 3/31/18 and noted to apply only to this instance forward.
  4. This preserved the 12/30/17 instance (correct), created the weekly activities through 3/31/18 (correct), but seems to have made all activities in the set prior to 12/30/17 disappear (ARRRGH)!
  
  Any idea what may have gone wrong and how to recover? What I described above is actually the situation for about 300 activities all together (I just gave one example).
  
  We use WordPress and latest Civi edition.
  Thanks.
  
  P.S. We may have a backup, but if this is a bug or something unclear, I want to be sure others know.

  Activities have a fairly complicated pattern in the database, where the column is\_current\_revision determines what the actual version is. You migt want to check the civicmr\_activity table to see what the situation in your case.
  Also, if you have logging switched on that might help.
  Obviously if you have a backup that might be the quickest fix.
  
  I am not sure if this is a bug, best option to find that out is try your scenario in a demo version?
