What is happening:
First, during the first "wave" of enemies in training, only two hornets spawn instead of three. This means you have to go to another place with hornets to kill the required amount. Second, all the enemies attack the trainers instead of the player should you stay anywhere near them. Meaning the Stored Strike segment is not very immersive, if still completeable. Finally, once you have completed the quest, there still is a quest marker over the instructor's head. Also, the quest description is missing in the journal.
What should be happening:
Three hornets should spawn instead of just two. The enemies should always attack the player only, and not the instructors. The quest marker should disappear at the end. The journal should have all descriptions.
Steps to reproduce the issue:
Just go through the quest. (Actually, it may be possible to complete this quest without having to find that last hornet. When the hornets spawned the other times during the quest, there was sometimes two, and sometimes three. I believe this may be random.)
