How...strange.
The Progenitor doesn't have to be in the well that the ship died in, I just tested this out because I was under the impression that both ships had to be close to the Progenitor and the ability had to be triggered right before the death of a capital (making it near useless in my mind).
I loaded up a game where I had a lot of veteran capitals, moved my Mothership to my homeworld, then skuttled one of the capitals who was in the adjacent one. Then built a new capital at the yard where the Mothership was waiting, used it, and magic.
However, when I did the same thing again I had no results at all from the Resurrection ability, despite scuttling another capital in that same well.
If it's not too much trouble, can someone who has done it to multiple ships walk me through the process? Where the ships were in relation to one another, what order they are destroyed, etc.? I find this fascinating, I love Advent and their special abilities, but the loss of just one high level capital can cost the game for Advent because of how important they can be. The possibilities presented by this ability seem very interesting.
