Hello there. Sorry for my bad English. I wish to make a GUI trigger such that in order to achieve the quest I created, I must destroy two buildings. But the problem is when I specify the target through the Events of "Unit Dies", the quest has unnecessarily achieved just by destroying one, and when I destroyed the other building, it repeated the "Quest marked as completed" scenario. How to make the requirement such that the player must destroy two so that the quest will be marked as Completed ONCE? Thanks.
