Why isn't my Paladin resurrecting my guard droids?

[DGDobrev]

You guys keep on mixing the Paladin hero and the Paladin unit's descriptions - but I'm glad you're grasping it now

Amelie, Paladin class, with Resurrection SKILL level 3 can resurrect everything, even mechanicals, plants and black dragons. So she is:
"Capable of resurrecting dead troops, plants and even machinery."

The PALADIN UNIT/TROOP whatever you wish to call it, can resurrect only adjacent level 1-4 living units.

It is as simple as that.
