Wargasm bug solution
Light Tank Mission: When you are strong enough to go to the Desolate Road, follow Chaoyang City to the right. At the end of Chaoyang City, the system will prompt you that ahead is the legendary Desolate Road and tell you not to go there yet or something. Ignore it and continue. On the third or fourth map of the Desolate Road (I don't exactly remember if it's the third or fourth, you can try it yourself), there are two light tanks. Defeat them to complete the mission.
