HairyToeKnuckles

During Nyoka's companion quest, Star-Crossed Troopers, I needed 3 pheromone glands. I got 2 and, on the third, the Primal jumped up right as I killed it, and the last gland went on top of a building where I cannot access the top (see picture). I have tried many times to climb it, but I cannot; thus, I cannot complete this quest. As a crazy completionist, i need to get it somehow. Thanks in advance.
