This does sound like a display issue, as we are not seeing this in the actual game records. We have passed back to the developers that the app players are finding this confusing with the graphics, as they differ considerable to the browser version with this new effect.  

To confirm this is not a bug, simply the new display for the change in the Twilight Phoenix feeding effect.
Please bear in mind that for Units damaged in Combat this will revive the Squadron, but for Units wiped out this will have no effect, as its not a Necromancer anymore  

This is 63 points: 1 for each Spirit Essence, 2 for Spirit Guards and 3 for defeating a Boss. This is why it is 1330 or more for Gold.
