When merging constituent records, where one of the records is the acknowledgee to a tribute, the acknowledgee relationship is removed from the tribute record.
We are currently evaluating this issue and will update this article when we have more information.
Steps to Duplicate
1. Jill is the acknowledgee to John and a constituent in The Raiser's Edge. 2. Jill is a participant in an event downloaded from Luminate Online. 3. Jill now has 2 constituent records. 4. Go to Admin > Duplicate Constituent. 5. Merge the 2 records. 6. Go to John's record and open the tribute. 7. Jill is no longer listed as the acknowledge.
