For the An Organic Solution quest have made my way to the Southampton estate and found Ella’s body upstairs. I tried to loot the research from her body but nothing happens. The quest marker is still on her body but the research is no longer on her body so I can’t collect it. I tried reloading to a different server and the research was back on her corpse again but the same thing happened when I collected it.
This quest glitched for me too. Maybe it isn’t a glitch, who knows. Check your inventory under the holotapes section. Ella’s research should be here. If you play it, it will load up a computer program on the pip boy where you can continue on with the quest. The objective of “Find Ella’s Research” will remain on the screen for some reason though.
