Combat not working PHP 8 fix

[OceanicNomad]

Instead of dynamically creating the fighters property as in previous versions of PHP, we need to explicitly declare it at the beginning of the class.

XG-Proyect-v3.x.x/app/Libraries/BattleEngine/CombatObject/PhysicShot.php

Line 62 in d1d9dc7

$this->fighters = $shipType->cloneMe();

Add private $fighters; below

XG-Proyect-v3.x.x/app/Libraries/BattleEngine/CombatObject/PhysicShot.php

Line 42 in d1d9dc7

private $cellDestroyed = 0;
