Engineers

    * Engineer Drone behavior improved.
    * Fixed a bug that allowed Repair Drone to be used at no cost.

    * Engineers should no longer erroneously receive bonuses from items which grant the Overshield skill.
    * Summoned pets should no longer fail to spawn when summoned.

简要翻译下：
*雄蜂的行为改进了
*修理雄蜂不需消耗法力的bug修正了
*雄蜂自动跟随主人升级到正确的级别
*雄蜂重新召唤后恢复正确的生命和技能奖励（也就是说以前那种刚进游戏的时候换装备招唤雄蜂，只要不退出游戏以后招出来的雄蜂都不变的bug没了）
*雄蜂从装备的护甲词缀中得到护甲奖励（可能是指和召唤一样，装备上加强魔宠的属性对雄蜂有效）
*雄蜂得到两倍护甲的bug修复（！！！好不爽啊！！！）
*修正了治疗附件强化和能量护盾发生器强化的bug，使效果按级别提高
*修正了破盾技能物品对工程师的奖励错误（不太清楚原来的错误是什么）
