ACU Bug With GroundFire & OC

**Describe the bug**
The Aeon, Seraphim, and UEF ACUs _move_ to the target location of a groundfire _if_ they have Auto OC enabled.
When Auto OC is disabled, the ACUs can groundfire properly.

The Cybran ACU does not share this issue.

---

**To Reproduce**
Sandbox Game:
- Spawn in an ACU for each of the 4 factions.
- Enable Auto OverCharge
- Order the ACUs to groundfire.
- Observe ACUs.

---

**Expected behavior**
ACUs do not move, but instead, groundfire properly.

---

**Additional context**
If groundfiring first, then enabling Auto OC - the ACUs ground fire properly.
The bug can reoccur when you override the groundfire order with another groundfire.
