Inconsistency - Gust spell moves corpses, but only when one target is alive

Reproduction rate: 100% Blocker ? No

Details:
Gust in combat will move corpses, so long as you're fighting at least one live target and the Gust spell pushes it back as well. However, if all your targets are dead, no corpses will move; creating a inconsistent effect (there's no reason why it should happen in one instance and not the other).

Steps to reproduce:
Use Gust in battle where you have one live target and nearby corpses, and again when you kill the live target.
