Units dont move to center of arena

[NightMagi]

i have this trigger:

• w12
  • Events
    • Time - Timer expires
  • Conditions
  • Actions
    • Countdown Timer - Destroy (Last created timer window)
    • Unit - Create 10 Spider for Player 12 (Brown) at (Center of spawn 1 <gen>) facing Default building facing degrees
    • Unit - Create 10 Spider for Player 12 (Brown) at (Center of spawn 2 <gen>) facing Default building facing degrees
    • Unit - Create 10 Spider for Player 12 (Brown) at (Center of spawn 3 <gen>) facing Default building facing degrees
    • Set Creeps = (Units owned by Player 12 (Brown))
    • Destructible - Open Rolling Stone Door (Vertical 3) 0002 <gen>
    • Destructible - Open Rolling Stone Door (Horizontal 3) 0000 <gen>
    • Destructible - Open Rolling Stone Door (Vertical 3) 0003 <gen>
    • Unit Group - Order Creeps to Attack-Move To (Center of arena center <gen>)
    • Wait 10.00 seconds
    • Destructible - Close Rolling Stone Door (Vertical 3) 0002 <gen>
    • Destructible - Close Rolling Stone Door (Horizontal 3) 0000 <gen>
    • Destructible - Close Rolling Stone Door (Vertical 3) 0003 <gen>
    • Unit Group - Remove all units from Creeps

i have 3 spawning places:
-Left
-Right
-Top

the units spawn at all 3 places.
All units from the Left spawn attack-moves to center.
ONLY 1 unit from TOP spawn attack-moves to center.
NO UNITS from RIGHT spawn attack-moves to center.

tried with Neutral Hostile but then the creep just move to the center and goes back to the spawn place

whats wrong with my trigger?

> Unit Group - Order

This has the same limitation as when you select a group by hand, it only applies to at most 12 units.


Why not put the ordering to a different trigger?

Event:
- A unit enters <region>
Conditions:
- (Owner of (Triggering unit)) equal to Player 12
Actions:
- Unit - Order (Triggering unit) to ...
