The avenger buff no longer applies to certain units with veterancy

[FurkanAdmin]

During testing, we discovered a consistent issue regarding the Avenger's attack speed buff interaction with unit veterancy levels. The Avenger's buff fails to apply to certain(we tested with quads and humvees) units once they reach a veteran status, whereas non-veteran units receive the buff normally.

Observed Behavior Across Test Clips:

Video 1 (Veteran Quad Cannons + Avenger): Quad Cannons with veterancy do not receive or benefit from the Avenger's attack speed buff while in range.

Video 2 (Non-Veteran Quad Cannons + Avenger): Quad Cannons without veterancy correctly receive and benefit from the Avenger's attack speed buff.

Video 3 (Veteran Humvees + Avenger): Similar to Video 1, Humvees with veterancy fail to receive the Avenger's attack speed buff.

Expected Behavior:

The Avenger's attack speed buff should consistently apply to units regardless of their current veterancy level.

Additional Note

In addition to testing against structures, we also tested these units against each other and observed the same behavior.

Quad Cannon	❌ Stops working from Veterancy 1 onward (Vet 1, Vet 2, Vet 3).
Technical	❌ Stops working from Veterancy 2 onward (Vet 2, Vet 3).
Humvee	❌ Stops working from Veterancy 2 onward (Vet 2, Vet 3).
Laser Tank	✅ Works at all veterancy levels tested.

Veteran Quad Cannons already fire at the maximum fire speed. The minimum DelayBetweenShots is 2 frames. See #56.
