Change Details

As a result of merging separate donor records, it appears that some donations have been deleted from Civi. The donor in https://civicrm.wikimedia.org/civicrm/contact/view?reset=1&cid=14806142 had three previous recurring donations, and we merged the donor records. Now we no longer see the 24 total contribs from three previous recurring donations GC IDs 3691024754, 4114417379, 5631603490 and only see the first contrib from the new one, GC 9501338837. We can manually reenter the missing contribs, but are there ways to revert whatever happened and more importantly to use the change log (or another process) to determine what the error was that caused the donations to be deleted?
