Whenever if the cooldown has ended, please force the vehicle to spawn.

A player committed an act of aiding the enemy by placing a gadget at the attack helicopter spawn point to prevent the vehicle from ever reappearing. Friendly gadgets cannot be destroyed, so attack helicopters never spawned again in this match. 
It's true that this player is a shameless, malicious player (His name means "Poop Man in Japanese"), but the fundamental issue is that if an object(include player) exists at the vehicle spawn location, the vehicle won't spawn even if the cooldown has ended. 
For example, in BF3 and BF4, vehicles would always spawn as soon as their cooldown ended, whatever the situation.
All you need to do is recreate this good old system.
Alternatively, as a compromise, please change it so that it can destroy friendly gadgets
