Inability to complete the quest cataclism 4.3.4

Playing as a goblin priest
At the starting location I had two problems
The first one is in the quest where you had to hit the ball on goal,
The goal just didn’t pass, 200 times. Only after a very long time I could still, though it’s not clear why it didn’t pass before, but it cost me a lot of time.
The second problem is related to the quest, where you need to use quick treatment 3 times on wounded NPS. When I got to that quest, the others were already completed and there were no wounded NPCs anywhere. The treatment of other wounded NPCs certainly did not protect. At this point, I tried everything I can, but in vain.

Please, send me the links to bugged quests (from wowroad) via PM.
I will inform our developer.
