If unit creates energy source after death with either editor option "Create EnergySrc@Destroyed" or by PRPL, resulting energy source has "EnergySource(Clone)" as unit type. I was told that Virgil tries to eliminate excessive "(Clone)" types.

Attached - test map (editor and finalized) with PRPLCores constantly informing what unit types are present on given coordinates.
Thanks for the test map. Made it quick to confirm the fix. Will be fixed in the upcoming build.
